A/C blower-fan cutting out
Ok, when driving down road with a/c on and I go up a hill , pass a car, or give a little more gas the a/c quits blowing out of vents. No airs coming out, but when I crest the hill or let off the gas the air starts blowing out again. Sometimes it comes back on right away sometimes it takes a little while. Anybody have any ideas.

You have a leak or your vacuum bottle is bad,when you accelerate you loose engine vacuum and any problem in your vacuum system will be more noticeable. Start at the intake and trace it to the vacuum bottle in the bumper and back to the heater control valve and vacuum switch in dash,the vacuum bottle itself maybe the issue,it has a check valve in it and they go bad also.

Ok great, I'll check that today, I just had a new engine put in so it must be back towards the vacuum bottle. Thanks
