My 97 XJ 4.0L auto 4x4 3.5" lift on 33x12.50r15 stock axle gears has its air blow out the defroster only sometimes in certain situations. It mainly happens at highway speeds 55+ mph going uphill and getting deep into the pedal but not too deep as to make the transmission kick down a gear. I have looked over the vacuum tubes and all seem well and the vacuum canister is not cracked. I know that with a vacuum leak the air defaults to the defroster all the time but my problem is it does it only sometimes. Any ideas on what this could be? It is really annoying and I would like to get it to quit.
