Re: Newbie: 2004 GMC Sierra P0650/P0496 Oil Pressure Gauge Malfunction?

Another thing I just noticed. While driving down the hwy it all of a sudden started blowing hot air out of ds only. It did this until I put it in neutral, shut it off and started it back up. As soon as I did that it started blowing cool air like normal.

I had ac/heat off. The fan was set to 0. Any ideas?

Also anyone ever seen a crew can sierra Z85? Mine has the decals and rpo code but I can't find another one like it online anywhere. Previous owner said it was special ordered.
