Help / Question

[thsf121821]

Ill give u the story and then someone maybe able to understand and help, but hurry cause my windshield is gettin awfly steamy. about two years ago i was at a red light at a dead stop and a "f"ing Cadillac rearended me at about 40 mph. I walked away without a scratch but my frame was bent and some stuff had gotten screwed up in the car, his was totaled and he had to go t the hospital. to this day, i only get heat out of the floor vents, i have worked for hours trying to get the switch to work so i can defrost my windshield but i cant make it happen. i spend alot of cold days driven around with my window open. it sucks. any help on fixing this problem would be awesome.
thanks

What year truck?

Most likely a broken/missing vac. line or if it's a newer truck...the control panel itself.

Or.....the "shock" of the accident broke or messed up the "flapper" in the ducts.

Why did'nt you have ihis insurance fix it if he rearend you:think:

[thsf121821]

the insurance managed to fix alot of it, and i had a rental car for about 9 months as part of it, but a few things they did not take care of which leads to a longer story, i thought it might be the vacuum but i aked that earlier on the schematic thread and i was sent a response saying it is all electrical and that there are no vacuums, let me knwo what you think and let me know if u have know of nay good sites with schematics for a 4*4 95 4dr Tahoe. thanks

They are right...it is electric. Do all the other functions work like they should on your climate control panel?
