I have a 1967 Camaro with factory air and a 327 with a 2bbl factory carb. Actually the whole car is original and stock. The A/C blow good and cold but I cannot shut it off. The heat also works fine when I move the slide on the environmental panel. When moving the top slide from cold to vent I hear the correct sucking sound (vacuum I assume) but when I move it to "off" and the blower switch all the way up the blower still blows cold A/C just very slowly. I've tried to figure it out in both park and while driving. I've only had the car a week so I'm not familiar with everything yet. The owners manual says (paraphrasing) the A/C will always be on and work with the heater for a type of all in one system EXCEPT in the off position. I already ordered the wiring schematics and build book. Just driving me nuts it's not working the way it should as it is interfering with me doing a proper tune up. Thanks in advance for any help!

Chris, Im moving this to the Heating / Cooling section, more of those guru's hang out in there :)
Welcome to Team Camaro too. Post some info. about your self in the Welcome Wagon section when you get a few min. :D

Thanks! I got so excited I didn't look through all the sections. Sorry for the inconvenience.:thumbsup:

Thanks all for your help. I got it figured out. Believe it or not, it was the blower shut off relay. I used this web site to find the problem... http://www.gvtc.com/~rlaa/ This guy has awesome schematics on just about everything!

That's Geezer's site! Glad you got it figured out!

Hey Chris,
FYI. Buy the Factory Manual and you will have all that.

I ordered everything I could get my mouse pointer on. The factory manual has helped me with some other stuff as well. Much better then any Mustang manual I've had. Thanks!
