Vacuum leak is causing max A/C problem.

[iwondupe1]

Hi Guy's, I have a vacuum leak I think, I went to the parts place because the check engine light was on, the guy there looked at the codes an said I have a vacuum leak. I noticed that now when I accelerate on maxth a/c shuts off the vent. I went fishing pulling a boat up a bridge an it shut down the a/c vent. When I switch it to the other a/c setting it worked. My question is how do I find it an the best way to find the vacuum leak I'm pretty handy under the hood an with tools I do know my way around a car not much computer wise but I don't think thats my problem. Thanks a bunch!!

Welcome to this forum! I've moved your thread into the A/C & heater section. It sounds like a hard plastic vacuum line might be broken. They usually break at the point where they connect.
