Suspension lift, larger tires, and stock gears affecting AC?

[xjaholic]

Anyone out there have trouble with the AC blowing mostly out of the defroster every time you accelerate or maintain hwy speed? My ac blows cold, but hardly comes out of the front vents. I am thinking that there is some kind of vacuum problem since I am running 32 inch tires on the factory 3.55 ratio gears. Any other ideas?

Has nothing to do with the tires. You gots a vacuum leak somewhere. Have you messed with the stereo lately? You might have screwed up something on the A/C vac harness. Do you have cruise control and does it still work? Try hooking up the vac hose to your A/C control directly to the vac port on your intake. Split the vac system into smaller sections to troubleshoot. Maybe your vac switch in the A/C control is shot and leaking. Check all of the vac circuits from the A/C vac control to see if a diaphram on an actuator is leaking.

Vac leak. I have it too

I never run AC though. Always roll the windows down.

I tried tearing everything out and going for a test drive. I thought that maybe there was a crimped vac line behind the ac controller. NADA. I am probably going to have to take it to the dealership for a service. Cant stand the heat and irregular AC anymore. I have to run the wipers in the morning because it runs in defrost all the time and builds condensation up so bad on the glass. Thanks for the help all.

Try checking your vacuum canister on the front bumper. You may have knocked off the vacuum line or cut a hole in it. This canister is what holds vacuum under different engine speeds.
