1995 Olds Cutlass Supreme Sl Need Help

Everytime I Turn On The Ac And Have The Knob Set So It Can Blow Air Front Front Vent It Will Work For 15 Sec And It Will Start To Blow From The Bottom And The Top Does Anyone Else Have This Issue . 2 When I Put The Car In Reverse I Get A Clunk Sound Need Advice And Last Is When I Start The Car I Hear A Small Clicking Noise From The Motor Sounds Like The Air Vent Flaps Are Shutting Ang Help Would Be Great Thanks

If the car was RWD, I whould think it would be U-joints, but its not...so Id recomend taking a look at your drive-shafts/half-shafts Im not shure what they are called in FWD cars...
Do you have the recirculation function turned on?...it looks like an arrow going in a circle and it recirculates the air in the cab...
If that isnt the issue, try puttine the AC on other settings and see if it does what it is suposed to on those settings...mabe there is a glitch:licka:

you have vacuum leak next to your battery. Take your battery out which isn't too plesant. There is a thin black vacuum line that runs next to battery towards the drive. Look for rubbing marks. If you can have someone with a syrine and blow thru your vacuum soures. you can hear leaking. good luck

Thanks Man It Was My Vacum Ball The Line Was Broken Thanks
