    HVAC O-Rings

    G'Day! Can answer if the green o-rings are supposed to replace the aluminum washers with the black rubber core? I ask for a couple reasons. First, everywhere I look, the green o-rings are plentiful while the others have to be special ordered. Secondly, I am having a hell of a time getting my...

    AC Compressor Removal

    I have a 1995 Hoe LS 4dr/4wd I'm having some issues with. First question would be, is it feasible to take out the compressor entirely and use a shorter surpentine? If so how long of a belt would I need. I don't need AC and a little better MPG would be nice

    05 Tahoe won't blow cold air

    My Tahoe blew cold air up till this summer. It has dual front climate control. I tried to refill it and it still doesn't blow cold air. I'm at a loss. The compressor I don't think is spinning. The belt spins around it but I don't think it moves. I'm not to familier with the A/C system. So I hope...

    New issue popped up today with a/c

    Until today, a/c ran nice and cold. All of a sudden, front a/c stopped blowing any cool air. But the kicker is that the rear a/c still blows very cold air. any thoughts on the source of the issue? I'm hoping it's a simple fix. Keeping my fingers crossed.

    A/C randomly stops working, then starts back up.

    My interior fan will stop blowing completely, on all settings, (a/c, heat, normal) It doesn't happen very often, maybe once a week (I drive about 350 miles/week), but it will stop, and then start back up on its own. I am not sure if this is the cause, but the very first time it started...

When I stopped...

    The a/c blower on my 99 Tahoe quit working on low and medium speeds but would workfine on high. Next it was intermittent on high and now it doesn't blow at all.
