[@madscientist4578]

Concise,informative,and a big help for me. I'm working on my first Benz- a C220 1995 model.

[@direccioneoideorgiva]

[@patrickcraig618]

[@jahblessin3996]

[@newtonraymond77]

6:08 good tip for people with dual zone. Great video brother

[@zefrimohd2619]

Is that possible to change the display from °F to °C vice versa? Thanks for the video.

[@ToddtheLoneDroner]

Sweet dude thanks a lot and now blows call there

[@sincerity7]

Hey is there a way to reset the flaps, I believe some of mine are stuck and or malfunctioning

[@newtonraymond77]

Did you switch the positions of the radio and climate control? That's neat though

[@PatsCarGarage]

I had to when I put the Continental radio in, the upper slow has a separate plastic frame that can be modified to fit the frame the Continental radio comes with. This gives it a tight fit and allows the Continental specific radio keys to work (so you can't bust in, yank the radio out and leave with it).

[@sincerity7]

​@@PatsCarGarage what radio was it?

[@sincerity7]

​@@PatsCarGarage is there a way to reset flap function

[@PatsCarGarage]

@@sincerity7 Continental TR7412UB-OR. I've got a review on my channel.

[@PatsCarGarage]

@@sincerity7 No, if your flaps are malfunctioning, you need to replace them. I have a video on my channel for that too.

I have a 99 SL500 do you know where I can find the codes/instructions for it? Thanks in advance for any assistance you can provide!!

[@PatsCarGarage]

Which codes are you looking for?

[@ddau6255]

I have a 99 SL500 too, AC not working so would like to know too

[@waheed521]

Hello, i have a Mercedes W202 C200 1999 automatic transmission , i have A/C issue with, when the A/C is on it is hot, not blowing cool , if someone know how to fix please guide me. thank you.

[@PatsCarGarage]

Get an A/C technician to diagnose and fix your car, it's the quickest and cheapest way to get it fixed.

[@waheed521]

@@PatsCarGarage Thank you.

[@MikeSmith246]

Thanks for the great video, I have a C280 withe same AC control, my center dash vents does not open, is there a code for that within the control unit? Thx

[@PatsCarGarage]

Scroll through the video's description, all the codes are there. I've also got a video on how to address vents not working (it's a big job, but totally possible to turn it around in a weekend if you have a garage)

[@yavuzsanane2077]

@@PatsCarGarage thanks for video. my car is w202 1996 model. My car's climate control unit is the same as yours. I have a problem. always the same fan parts are blowing in the car. center console fan not blowing. step control does not work. it always blows the same way.

[@PatsCarGarage]

@@yavuzsanane2077 you should vacuum test the actuators make sure they aren't leaking

[@craigodell6358]

Does anybody know what version code you are suppose to have related to year and model? And does it have anything to do with the software status code?

[@PatsCarGarage]

Well basically, if you read the description, you'll see all the possible version codes to use. You have to figure out what equipment corresponds to your car. Pre-facelift all uses 00P because there is no K2 serial interface on pre-facelift cars. 08P should only be used for diagnostic reasons on pre-facelift (same for 10P on facelifted cars). If you have a facelift, you'll either use 02P if you have a fan clutch, or 18P if you have an electric engine cooling fan. 32P would be for fan clutch without aux fans (I've never seen a car with just the mechanical fan). I'm guessing it's used as a temporary mode if the aux fans / fan controller are broken. The engine can get quite hot if you are idling with the AC on and without aux fans.

[@waleedwaleed5251]

How do I set the outside or inside temperature to the climate control panel?

[@PatsCarGarage]

you don't

[@mohammadalomari4924]

Good video but I prefer not to play with these codes it's not easy to set it up again

[@PatsCarGarage]

You should be fine as long as you are careful with the version coding menu, for the 2 other menus, there isn't anything you can do which will break something.

[@ThePersonSwing]

how to check which version code i have? what 42 shows?

[@PatsCarGarage]

watch the video

[@marceloroggio4996]

do you know how to change from Fahrenheit to celsius?

[@raulsd6047]

Hello everyone, I replace the condensor,compressor,canister and expansion valve , i pull out vacuum for 30 min and add (12oz ) about i can of r134 freon with the engine off, now I start the car and the control does not move from 72 degrees so the compressor does not engage to recharge any idea how to fix/reset the temperature control? Thank you

[@PatsCarGarage]

One can of r134a is not enough. I don't know which model you have but Mercedes of this vintage typically require 2 cans (sometimes a little bit more). With that being said, even with 1 can, the compressor should start, I suggest you follow the procedure from my video and find what the error codes are.

[@raulsd6047]

I MEAN THE Climate control I think needs to be reset

[@ELdanizz]

00P what is this?

[@PatsCarGarage]

Look in the video's description, I have a breakdown of everything.
