I have a 2001 Chevy

Aug 02, 2008

- Today I checked behind the glove box (real easy in 2001 Blazer by moving upward a glove box door stop lever on the top left side of the box with the glove box door in open position and pulling the door past the stop. I made certain that all the vacuum lines were properly seated on the vacuum controls. I also removed the cowling around the heater control/radio, etc., and moved the cow,ing out of the way enough to then pull the heater/air conditioning control center (fan speed, temp control, and off, max air, air, heater, defrost controls) out by removing two screws. I removed every electrical connector on the back of the three control switches, checked for any connector contact corrosion, and finding none, replaced all the electrical connectors. I also made certain that all the vacuum lines connecter to the back of the air/heater control switch were properly inserted and there were no leaks.

Although I did not find any apparent problem, the system now works properly and we have the high speed fan working on air Max and Defrost.

Thanks for the posting
