the ac worked great until the airride. I moved the parts off the pass inner fender and don't know if I have swapped wrong hoses around or what. I had to undo "PURPLE, BLACK, & GRAY" wires & relocate them.

Now the dash controls don't seem to do anything other than select the fan speed. Air only blows at feet and hot air. When I select anything that involves the ac comp I can hear & have checked that the comp is still coming on but blowing hot ac air.

what have I done? please help me!!!!

thank you

I will post pics in air ride section of car

Sounds like you might not have any vacumme to the controls. The short black line goes from the intake to the round ball mounted right by the heater core, the pink line also plugs into the ball. Grey line goes to the valve inline with the heater hoses.

No need to take anything apart, it should be in the engine bay right by the heater hoses.

I already had glove box out so i dropped interior trim by ac box & noticed temp cable was moving back & forth but seems like everything else is vacum so I wasnt sure how to check.

Here are the 2 hoses 1 pink 1 gray coming from pass side


here are the pink hose & a black hose, is this what you are calling "round ball"? im not seeing anything ball like unless im blind


here is the valve with gray hose connected underneath


are these right?

That piece you have pictured is right, most are a round tank about the size of a softball. Where is the black line connected too and if you take the black line off the tank with the car running is there vacumme there?

Ok, check the tank for cracks, if that's OK you will have to remove your controls and on the back there is a round piece mounted right on the controls. If you are getting vac to that piece its likely that selector is bad. They are commonly get dried out over the years.
