When I accelerate hard my A/C stops blowing. I suspect it may be a vacuum problem closing the air circulation door. Any ideas how to diagnose the problem.
I also have a "Check Engine" light that AutoZone says is an EGR problem. I know the EGR valve is vacuum controlled, could the two problems be from one cause or just coincidence.
I had the same problems with both, I have a 4.0L V6, according to my mechanic the AC is suppose to cut out when you stomp on the accelarator, I had to replace a sensor for the AC because it got burned out by doing so. And no on the EGR valve. I replaced it when my check engine light came on also.
