The only way to get this is from a Salvaged Truck. I Still have my cd Player in My 95' Silverado because I could not find one Either. I went ahead and Installed the Aftermarket System and just unhooked it.

SOURCE: How do you fix the driver side air blend door actuator?

you cannot repair the actuator you need to replace it with new one. These motors turn but get weak with time. if you test it, it works, put it in and it doesn't. this is because the motor is weak, unfortunately GM does not sell these motors separately.

SOURCE: Air conditioner blows hot air after 30 seconds on

I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.

Rear heating problem


Hi Jeff. I had the same problem, along with others on my 03 Denali. Along with not blowing hot air from the rear heating system, I had hot air blowing out of the passenger side and cold air out of the drivers' side vents. My battery would go low and had the same smell. I took my Denali in to the dealer and they found it was a bad Fan Control Module. They replace it and everything worked well after. It cost me $293 for parts and labor. Hope this helps.

Have the FAN CLUTCH checked. they are a common failure. Get a AC DELCO or the part from the dealer. Why was the radiator replaced? Heater work OK? A/C works OK?

When the heater is on there is a very strong natural gas kind of smell inside our 2005 Yukon Denali. It seems to come from the vents... and seems to be worse when slowing down or idling. Had the vehicle...


Check under the hood and make sure there are no fuel lines leaking.You should be able to smell it.If you don`t know what to look for the take it to a garage or your dealer and have them look it over.It is not safe to drive if you smell fuel while driving.It could cause a fire under the hood.Good luck.

The rear heater does not generate heat - only cold air in vents


does front air work properly? for heat i mean?.. the blend doors are suspect as well as the heater hoses to the rear core and its heater valve.. possibily the control head is to blame or?, but i cant tell from here
