New guy with some isues

[pricey59]

I have tried to search for these topics, but the search didn't narrow it down, so if this is a repeat....sorry,

I have a 2000 Yukon, and here are my issues...

1. I have no heat in the front, it will only blow cold air but the rear blows hot.

2. My fuel gauge only works some of the time. Some time it just goes up and down, but usually it sits on E.

Any help would be great. Thanks in advance

Do you have the digital climate control? If so, the little flap actuator that move it from hot to cold may be broken.

I know the gauges have been known to fail on these from time to time. Not sure if it could be that or a bad sending unit. I'd guess one of the two.

sounds like sending unit , and agree, door on heat issue.

Oh, and welcome to the site
