no lights or display on heater control, FIXED.

[@TheHeadlessHorseman]

Thanks for the video. I had mine atop on the way back from the beach. Just died, no lights nothing. Checked fuses, all were good, checked the wires you showed for power, they all had power like they should. Was gonna start looking for a new hvac module to replace it, thinking it was bad. Luckily I decided to try one more thing. I took an eraser, the flat beveled edge kind. Ran the eraser over the metal contacts where the plug goes to the climate control. The eraser cleans the contacts. Sprayed a can of dexotit on the contacts(Amazon has it, its electrical contact cleaner). Its now working as good as new. Maybe this will help someone else that is in a similar position

[@clintvaughn3826]

You helped me in so many ways it’s not even funny I had no clue why my control panel would not come on and that was the problem the whole time thank you so much!

[@anthonyhough1190]

Brother I was about to buy a brand new switch an I just checked what you showed, you just saved me time and money,I truly thank you👍🏾

[@tadshackles]

Dude you’re the man. My bro just bought a 91 chev 2500. Couldn’t figure out the heater issue. This worked like a charm. A relay is ticking off and on in the dash we gotta find now but heater works. Love you.

[@juanitatoole9332]

Thanks a bunch my 92 Silverado is just like this... no display on HVAC system so I'm going to check the wire behind the ashtray, 2 see if they're melted... thanks for posting this video I didn't know what else it could be!

[@tli4413]

Thanks man one wire was fried and also hvac module needed to be replaced now it works like new. 1994 chevy 1500 thanks for the info

[@GMoye-uj4nt]

I, too, have a '92 Suburban. The fusible link that controls the a.c./blower burns out at the junction block underneath the hood. Also, to the Headless Horseman, check your relay and headlight switch connector to see if it has melted. If so, it might be the fusible link at the battery junction fuse block.

[@austinblanchette5311]

Just here to pay my dues. I had the exact same problem and symptoms and similarly my connector was burnt and corroded. I bypassed the connector and put the wires together and it worked aswell.

[@vasquez414starr]

Bro, thanks for posting. My display went out. Just hard wired and now fixed.

[@LarsonFamilyFarm-LLC]

Thanks...very informative....i'll go check mine now. Update...Yes...that's what it was (corroded connector, voltage drop)....you saved me a bunch of time. God bless you!

[@juanabernathy5371]

My 91 just went blank! Going to try this. I'll keep you updated. Thanks for the info.

[@derrellgarcia8522]

Thanks a lot pal, my truck had the same problem. I fixed it ,thanks for your help👍

[@matthewfishingtv8169]

[@khrukmstrflex1522]

Brooooooo!!!!! Youve SAVED my ass!!! I been replacing parts reluctant to chase wires. Mainly cause im not intelligent when it comes to electrical. Thank you soo sooo soooooo much!!! This was the problem on my truck. The whole connector was melted

[@AMDingmann]

Very good video. Never would have guessed

[@chicagoblackmale]

[@SamuelJMoe]

I will try this after work thank you

[@88chevyman4]

Thank you it helps a lot I made a video as well to help with the power problem

[@xaviervarnum2252]

My 91 GMC Sierra the same way gonna give it a shot

[@OBSbryan.]

the red cable on my ac has no power, i have not found the problem, do you think it is that connector or has to do with some other cable

[@leoleonel6234]

thanks checking tomorrow u r the man !

[@FreshKicks4545]

Just to make sure. U basically took out the connector. And spliced the wires together?

[@mikefisher4569]

You just saved my ass man. Thanks

[@BondJonahBond]

What’s the name of that connector? I’d like to replace rather then remove it.

[@jcahreevdy5940]

thanks brother. fixed mine.

[@BARBARRIER]

jcahreevdy just saw ur message. Glad it helped.

[@joshuamcneal5515]

Saved my life good video & info I also gave u a like & subscribe

[@BARBARRIER]

Your welcome guys. Glad it helped.

[@timjones6231]

Did the unit stop blowing air too

[@wadeross]

Found the problem, thanks!

[@avestruz9259]

thanks a lot fix my problem it was the same thing

[@louis48ful]

Mine is doing the same thing but haven't had time to look....do you think it's the same thing? Because I couldn't find a fuse for it in my truck

[@rebel937]

Thanks, that was exactly my problem

[@BARBARRIER]

rebel937 your welcome. Glad it helped

[@OscarSancheezy]

GOATED

[@fishingautos8585]

Thanks dude that's my problem.

[@BARBARRIER]

Aaron Dybevik no problem man. Glad it helped.

[@louis48ful]

Did the connector also cause a short?

[@tahoe6182]

Does any of yalls turn on then maybe little later just shuts off trying to figure out why my does that

[@xaviervarnum2252]

I just installed a new unit still not working could it be that connector

[@brianoxendine4844]

Sometimes mine won’t get power doesn’t light up or anything but if I tap it a few times it will start working again any idea???

[@claytondavis4899]

Thank ya man the fix mine

[@BARBARRIER]

Clayton davis glad it helped man.

[@professormoriarty1576]

Wait, did you connect all of them to each other, or each individual to it's corresponding wire

[@BARBARRIER]

Each to their own wire. color to color. Just hold the plug together like it's supposed to be connected, then you can tell what gets connected to what.

[@Blue_Thang]

Thanks

[@aaflow903]

Do the same thing (way) works if the display goes out whenever the headlights/parklights are turned on

[@spensergomez6607]

Im going to go 5ry this thanks man

[@cyberdude721]

along with this issue I had another and it was a melted plug behind glove box(3 wire, red, green and light green) be careful not to ground the red wire( the actual one that melted connector) onto the computer body!!!!(and yes I should have disconnected the battery first but this was instant feedback when touching red wires together) This was my problem and once I cut the connector out, reattached the red wire my heater control came back to life, this is after buying another control unit,(old unit still good),and fixing bad wires as described in this video the control unit still did not work, I had to fix the connection behind glove box, all works now but I still don't have good heat I assume this is one of the 3 doors in the system, but hope this addition helps someone as these are a real brain buster since you cant find a good wiring diagram not even online and a Haynes/Chilton book forget it (worthless anymore)

[@davidtrejo4244]

Thank you ! For the tips.I found the same problem .in the back of the glovebox. You saved me a lot of time. Thank you

[@oscarpinedo3652]

Wat if the connecters aren't hot wen turning the egnition

[@johnmyers6802]

Anyone have an idea why it burned up in the first place? I did this but put a fuse in place of the black wire and it worked for a few miles then quit again

[@BARBARRIER]

Blower motors and heater components draw a descent amount of amps. Over time, the connections in some plugs and connectors can loosen, when current flows through the loose connection it will create heat. Enough heat will melt plastic.

[@xaviervarnum2252]

I'm gonna try it
