My C4 Corvette wont allow the heater or the A/C to come on. I replaced the control panel and everything on it works. Temp, blower etc: All fuses check out as OK. What's next in line to check?


Edward,

C4 Corvettes have an Outside Air Temperature sensor which may be faulty. It senses air temp in front of the car and tells the climate control unit (which controls the heat/ac) what the temp outside is. Yours is in front of the grill. It's a $20 part. It looks like the attached link. I'm not sure if this is your issue, but it was on my son's car. I just thought it might give you a direction to check.

Why is myelectronic climate control panel Dead No Lights no blowers no air or heat.


I like some of these answers these people post , I believe people need an want to have a little more info then that ! The guy can't even spell ! Neads -- needs diagnostic done on it , an what kind of diagnostics does it need ? Well lets see if I can shed some light on the situation ! I worked at a Cadillac dealership back in the late 80's . The climate control panel is electronic an is hooked up to the BCM - body control module another electronic control module an when operating as designed they communicate info back an forth but yours is dead an the BCM isn't see any info . an the BCM has the function of the security system probably too . An it won't let it start ! Your probably going to need a new climate control head ! This system is connected to diagnostics it's self , if you push the off an warmer buttons at the same time it will go into diagnostic mode an show codes , an do on vehicle self test . With out the service manual you can't do it yourself !

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Air conditioner clutch will not engage. also my car has auto climate control and the external temp. light always reads 30 degrees.


That is why the A/C clutch is not coming on.If the temp is below 50 degrees the auto control will not allow the compressor to kick in to protect the compressor.You have to check the codes for the body control module.It should show a code for the outside temp sensor.You could have a bad sensor or wiring.If you disconnect it it should show -40 degrees.check wiring and connections.Hope this helps.Good luck.

My instrument panel lights come on when first


Check on the front panel where you see fuel consumption, outside temp etc that the botton that says black has not been pushed. If pushed no dash lights will come on and the panel screen for the outside temp etc will also be black. So give it a push and the lights should come back on.

Climate control display for Outside temperature


Had the same problem, replaced the ambient air temp sensor in front of the radiator. Cost is like 10-15 bucks. Don't worry if temp doesn't change right away. Took me about 5 miles and then it worked great.
