1992 chevrolet c1500 silverado heater/ac control

LED lights in display on ac/heater control stay on when ignition switch is off. Control works properly when it works or sometimes does not work at all and then LED lights go out. I have found that if I remove the 25 amp htr/ac fuse and re-insert the same fuse (which is good) it seems to reset and work.

SOURCE: I have a 2005 chevy


Try this solution. I have had the same issue three times. A Chevy tech told me that if it keeps doing it, to replace the blower motor, as it seems to be a chronic problem with the blower having to much resistance and thus burning out the resistors. I suspect that you probably had lost one speed first and then more. It has happened both ways with me, once the entire thing went out at once and then the other times it goes one speed at a time.

SOURCE: Heater/ac switch speeds 1 and 2 don not work in 99 Silverado

you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .

Cruise control not working in my 2009 Silverado. It went out gradually over the past several months, pretty much worked intermittantly.

cruise control module has failed. or if your brake lights are staying on, then brake light switch has failed and not allowing cruise to engage. Have someone stand behind truck and see if brakes are working properly, if not- replace brake light switch. if fine, then swap out cruise control module under hood.... prob find one at a junk yard.

Speedometer, cruise light , ac/heater control doesn't work

Sounds like someone needs to do some more troubleshooting first. Changing the cluster is not a simple matter since your mileage will be different. And the cluster is on a different circuit that the ac so one should not affect the other.

2003 silverado ac only blowing from defrost.sometime it will jump from feet to dash , but goes back to defrost and stays .

The problem could be the vacuum line from heater control to the engine. Check where it comes through firewall and be sure it is connected. If ok problem is likely heater control switch.

Ac control panel!!

Does the fan motor blow when in any position for heater? It is very common also for the switch to go out in these models as well. The blower fan fuse is in the main panel under dash.

My 92 chevy silverado a/c light is flashing and the a/c doesn't work now

if you know system for a fact has full charge, The low pressure switch will keep ac from engageing, thus shut the system back off. it is simple to replace it is on the reciever dryer under hood on passenger side a silver cylinder you will see a switch like plug on the dryer this is a common problem.and they just unscrew and usually have a valve underneath that keeps you from losing freon if you remove quickly.
