when I turn the vent on or a/c the air flow comes out the top and bottom not through the vents like it should, when i mess with the switch it eventually works after some time..any suggestions on what I should do???

 

sounds like you lossing vacuum to your a/c maybe ?? check your lines for intake to going inside to the case ,,maybe you canister is leaking...???or got bad vacuum element??

 

yup, sounds like a vac leak. there should be a vac line heading into teh firewall from the motor. Make sure that has vauum. there should also be a check valve there. Make sure thats functioning. Then start inside and find where it's bleeding off. A hand held vac gauge/pump from autozone is a good tool to help you find this problem.

 

thanks guys I will give it a shot
