Hey guys

I have noticing my oil has been getting a bit of gas in it. I was wondering if it a vacuum problem.

Heres my problem, Whenever i turn on my MAX AC on high or on automatic it will blow fine for a bit then all of a sudden it will shut down and blow out from the defrost then it will go back into the vents again. Just wondering if this could be a reason why I am running rich. I would like to fix the AC problem too. I changed the AC cluster in the dash with another used one and it continues to do the same thing so I do not think it is the mechanism.

Thanks for the help

You just described the same problem I had a few months back. The first place to check is the fuse box. It's a silly little thing, but make sure the fuse is in good and you don't have a loose connection. I had to replace the module because the fuse wasn't making good contact.

Turn on the A/C, and when it shifts to the defroster, reach down and apply pressure to the fuse. If the A/C comes back on, that's the problem.
