C4 Corvette HEADLIGHT MOTOR REPAIR: 5 Useful Tips

[@bdevitt55]

I bought a 95 C4 from someone who had only done the driver side....so a year later the passenger side needed it. Thanks to your tips the motor repair went well!😀

[@RetroCarsForever]

Glad this video helped you out!

[@0xymfzzty0]

Always loved the c4s headlights, that flip is majestic

[@RetroCarsForever]

No joke, the C4's headlight "flip" was a big reason I wanted one!

[@themanguy2110]

I love how high-quality and informative your videos always are!

[@RetroCarsForever]

Thanks so much!

[@michaels5809]

My dad got our 94 c4 in 2009 when I was in kindergarten, and now I get to drive it and its a really special car to me. Your videos have been great as I wanted to understand the car since its always been special to me.

[@RetroCarsForever]

That's awesome to hear. C4s are quirky weird cars, and they are getting old and needing attention, so empowering yourself with knowledge about them is a great way to take good care of em. Enjoy your 94!

[@michaels5809]

@@RetroCarsForever Yeah haha its definitely having those “wait im a almost 30 year old car” moments but it was re built when we got it it was clean my dad “bulletproofed” it when we got it. It has 65k now, biggest issue is its leaking transmission fluid from the main seal but we’re fixing it soon. All the tech works I love the way the car feels.

[@RetroCarsForever]

@@michaels5809 C4s feel GREAT. Fast enough to be entertaining, comfy enough to be livable, but old enough to have that special raw/connected feeling.

My headlights on my 1986 convertible work great but its good to have this info for when it eventually takes a shit.

[@RetroCarsForever]

Heh, and these WILL fail eventually! Good info to know for the future I hope. And hey, you must have a Pace Car replica!

[@yomuno2511]

Good video. My headlight problem on my 1995 seemed to be unique. I purchased the car new (my 29th BD gift to me). About seven years/100,000 miles old, the left headlight did as shown here. I ordered the bushings. However, when I took it apart, the old bushings were fine. Posts on forums such as corvetteforum yielded no results. As it turned out, the metal shaft was free spinning inside the plastic gear. I drilled a hold at an angle thru the gear and shaft and inserted a pin to connect the two. Twenty years and 161,000 miles later and it's worked great. Right side has never had an issue. I will also add that the right side since new has always flipped faster than the left.

[@josephgibbons1631]

I rebuilt mine in January. Easier than one would imagine. Fun to do. I used Chris Fix’s video.

[@hambonerodriguez4163]

Hey, I always watch your videos on this car. I have the same one with the red interior. Mine is currently in the shop getting the Bose head unit replaced with a modern Kenwood unit in preparation for the Hot Rod Power Tour long haul. Can't wait!

[@RetroCarsForever]

Thanks for watching! Really cool that you have the red guts on your car, that's definitely the most rare/valuable color for the interior on these. Have fun on Hot Rod Power Tour!

[@RobEvans-o1c]

Came across your video and thought to myself, that's exactly what mine is doing. Checked out your recommended video and just finished it. Even had the bushings, apparently came with the car when I bought it 10 years ago. Didn't know what they were for so just put them away. Good job, Thanks

[@RetroCarsForever]

Awesome to hear! Glad this can be helpful to ya.

[@uPilot]

Great to see you back into videos, my dad has a 1986 corvette and both of our headlight motors worked but then we tried playing with wiring because the horn wasn't working and we accidently unplugged one of the headlight motors and we still haven't found how to plug it back in.... the other one works great and the one that doesn't work makes no noise since it's not plugged in.

[@RetroCarsForever]

Hmm, there's gotta be a way to replug that light in! Wish I was more familiar with those early designs to tell ya whats causing that issue exactly. Or maybe a wire just got pulled or stripped accidentally.

[@uPilot]

@@RetroCarsForever yeah, I recommend you try to do more content with earlier ones since not many have made content about those!!!

[@uPilot]

@@RetroCarsForever It's not a big deal, we usually only drive it to car meets and joy rides in the summer but it would be nice to find the right wire haha

[@speedracerjeff]

Great vid as always. Had to replace the gears in both my 88 and 92. Went with brass gears on my 88, and plastic gears on the 92. Both worked great and never malfunctioned again till I sold the cars.

[@wrongperson7363]

I bought my 1993 the beginning of 2023 with 106,000 miles on it and surprisingly the headlights work perfectly I did change them for LEDs, I remember telling you I was planning on buying a c4 as my first car best decision I've ever made

[@TofersCarTales]

Who would have thought I would have basically performed this exact same repair on my parents '91 Grand Marquis window regulators. Though I ended up using steel ball bearings. I did warn the parents that closing the windows with an arm in the way would not be recommended.

[@RetroCarsForever]

😅 Yeah, same basic design, right?

[@rluciano828]

Great video!! I did this job on my LT4 last year and you nailed it, skip the brass, watch the paint, make sure the motor spins. I never thought to calculate the time and compare to the mechanic shops. You think of it all. Your production quality is awesome and love the extras, especially your work buddy curled up for a nap. I'm surprised you don't use painters tape around the entire hood when removing the headlight. I didn't trust myself not to touch the sides on the top and sides when free.

[@RetroCarsForever]

Thank you! Gotta have my work buddy LOL Painters tape is a good idea, I didn't think of that one. I personally felt like I only had issues keeping the bottom edge from touching, the tops/sides were reasonably easy to keep clear. Still, you can't have too much protection for a job like this.

[@MarkVidal]

good to know! the lights on my 93 make a strange noise but luckily still flip up normally

[@RetroCarsForever]

That strange noise is most likely the beginning of the problem I go over in this video. It'll get worse and worse over time, until finally they wont flip at all, so hope this video helps you get on it soon!

[@jakeakhtar9424]

Thank you for pointing out the advantage of plastic gears as a mechanical fuse. I see plenty of people who feel that brass gears and/or bushings are an upgrade over the plastic OEM parts but ultimately, as you say, I'd rather replace the gears and bushings than the motors if something goes wrong. I rebuilt my headlight assembly when I bought my C4 and it wasn't a difficult job and probably took less than 2 hours but I was glad to have torx bits and that time doesn't include the time I spent going out to buy a pin that I broke while disassembling the assembly. All in it was still under 3 hours and very easy to DIY.

7:55 "schedule one full work day"... well you convinced me. Your one full work day is probably like three days for someone as mechanically handy as I am. So sounds like when that day comes, $400-600 will be worth letting a professional do it for me while I'm sitting in the waiting area drinking hot chocolate and likely drooling over the C8 in the showroom :)

[@RetroCarsForever]

Heh, fair enough! I feel the same way about many Corvette repairs, and am happy to fork over some extra money to let the pros do it. But this one was actually pretty easy and satisfying, even for someone as amateur of a mechanic as myself.

Hey, Im glad I have found your channel this night. Im a 04 GTO owner but I always dreamed about having a 1990+ Corvette C4 (I saw one when I was just 5 years old). I found a guy who is willing to exchange GTO for a 95 C4 and I can't decide... I know GTO is just a better car but I wonder if its worth getting rid of great car just to fulfill a childhood dream? :P Probably it's even hard to compare those two cars. Whats your opinion? I had 95 Firebrid Trans Am with LT1 for a couple of months but I exchanged it for GTO. I ask you as an expert - is aftermarket optisparks still a lottery or there are some solid ones to buy? Please just tell me to go for a C4 and that I should not worry that much :P subscribed!

[@RetroCarsForever]

I’ve never driven the GTO so I can’t honestly answer your question! They seem like awesome cars. I’ve talked to a few friends who have driven both and they said the GTO drives like a big heavy car by comparison. C4 apparently handles a lot better. I know there are satisfied Opti custom users in the FB groups im in tho I can’t recall what brands are best. Just don’t go cheap! Thanks for the sub! New video next week.

[@robs2341]

I guess if it ain’t broke don’t fix it as they say

[@RetroCarsForever]

So I got a 94 and I bought a new driver side headlight and when I put it in it still didn’t turn the motor is new and the gears are good what do you think it could be? The light does turn on but it just doesn’t turn. Pls help if you have any idea thank you

[@RetroCarsForever]

So the electric motor itself (that I go over in this video) doesn't actually spin at all? When you say you got a "new drivers side headlight" what do you mean exactly...An entirely new unit? New motor? What was new exactly? And how certain are you that it is for the correct year?

[@RetroCarsForever]

@@michealmartinez6644 So sounds like there's something going on with the electric motor then, if that top part doesnt spin at all. Or something wrong with the wiring to that specific part. I'd have an electrician look at it if you can. Otherwise, buying a new motor unit would be a "throwing parts at it" solution that may work. Honestly I'd be miffed at whoever sold me that headlight unit, and I'd want a refund! But too late for that I'm sure.

[@WebbRacingdotcom]

Great tips, Brad. I was patient with the repair, and I spent about the same amount of time as you mentioned. One thing I might add is to be careful with the Torx bolts, as I managed to strip one during the removal process when I didn't have the Torx bit fully inserted into the bolt head. Happy headlighting flipping!

[@RetroCarsForever]

Thank ya! Glad to hear I wasn't the only "slow" one with this repair...If Ive learned one thing about DIY car repair, its haste really does make waste. Good tip on stripping the Torx bolts, SUCH an easy thing to do.

[@foofghtr]

Great fix but for someone who was around when all these cars came out, your headlights are spinning too slow. They spin together which is good but way too slowly. Your HL motors are dying.

[@RetroCarsForever]

Strange, I’ve done videos with many other C4s and flipped their headlights as well, they are all the same speed. Been awhile since I’ve flipped the earlier designs so maybe those are quicker? Or is it possible that you remember them faster than they really were?

[@cliftongillyard1085]

I put new gears in my headlight motor and it opens fine, but won't close. What's the problem? 1996 Corvette c4

[@RetroCarsForever]

Strange! Before you swapped the gears, did the motor itself spin both ways?

[@cliftongillyard1085]

@@RetroCarsForever yes, and I still don't know the problem.

[@WigglyBot]

It's a long shot to ask but i thought id ask here anyways because I haven't found an answer yet. I have a 84' Corvette (84'-87' year headlights) and I'm having this problem I have replaced the all the gears and all three relays, but Im still having the notorious thumping problem when I close my headlight, passenger side, what else would be the problem? I haven't found anyone else with the same problem as me so whatever advice or tips is appreciated.

[@RetroCarsForever]

Hmm, I'm way less familiar with the earlier headlight designs so nothing springs to mind. Have you replaced both sides, and only one side is having the problem?

[@WigglyBot]

@RetroCarsForever Yes, both sides have replaced gears and are lubricated properly, but it's only the passenger side that's having the problem, usually if I wait a week until the next time I pop up he headlights I might be able to get away with flipping them once or twice before the thumping starts and it usually happens if I were to drop the hood closed. I have also taken apart the both motors to see if the gears i replaced them with went faulty fast but both, and more importantly the passenger side gears are still in perfect condition. So for now I just have the motor wires disconnected so I can actually drive without going crazy lol. As a solution I'm leaning on just buying a professionally refurbished motor, but I'm trying to do all I can to avoid that

[@RetroCarsForever]

Very strange issue! I cant think of anything that you havent tried (beyond buying a new/refurbished motor), assuming you put both sides together correctly. I would suggest posting this issue in any of the larger C4 Corvette Facebook groups. Super knowledgeable owners and whenever I'm stumped with a mechanical issue, I usually get answers there. Good luck!

[@WigglyBot]

@RetroCarsForever I'll try asking on FB next. I tried on corvetteforum but didn't get anything so ill hope for the best lol
