Re: A.C. Problems

To check the front temp control door do this:

1. Get the engine to operating temp.
2. Leave the A/C off!!
3. Turn the front blower fan on to med or high.
4. Select the upper vents for air discharge.
5. Turn the heat control to full hot-should feel hot air out of the vents
6. Turn the heat control to full cold-should feel air temp change to outside air temp.

If you don't feel any temp change at all the temp control door is inop.
