HELP?? A/C Stuck on Defrost and can't find broblem
I've seen that other members have had the exact same problem maybe someone can help.
My A/C defaults to the defrost setting. All of the other position seem to be O.K. but when A/C is on it goes to the defrost.
I'm baffled, I've gone over every inch of my vacum hoses with alcohol to search out a leak and don't find a thing . My vacum canister maintains its vacum even after a few days of not being driven. I've replaced both check valves that are in the engine compartment' I've spryed carb cleaner over every inch of my manifold and vacum line inches at a time to see if there would be any change in RPM's but nothing happend. I've pulled my dash apart to see if the temp and position control hoses are leaking and everything seems tight.
Is there something else to check? Is there a shure fire way to seek out vacum leaks? Is there a chance that it could be the EVR (electronic vacum regulator)? For now I've wired the vent door open but that's just a short term fix.
