Sooooo, it's friggen cold.
I'm basicly driving and have zero heat in the cab.
I mean COLD air.
I check my temps and all is good,
So, I pop open the hood, and see my
(Unplugged )a/c compressor is on/ running?
Lol, was basicly It was an ice chunk...
I tapped (love taps) the ac clutch,
And THEN she stopped spinning (staying engaged)...
But every bit shed spin a bit...
I got a compressor from rock auto, and wow!! On days like this was super nice to have heat again.....

Re: A/c compressor
Mind you in a H1...you use the term heat loosely...more like a warmish breeze...never hot...not like an H2!

Re: A/c compressor
My 99 HMC4 gets plenty warm. -30 no problem with a nice warm cab.
But yes the climate control I had in the H2 SUT was awesome.

Re: A/c compressor
i had similar issues but it turned out to be a bad vac pump and a ground wire on the blower motor. took about1 hour to troubleshoot and repair. hate to see what the bill would have been at a shop

Re: A/c compressor
Speaking of "Luke warm"
I find "even with my blend door closed" at times on the Hwy, whe will blow hot, then after a while, just Luke warm for a little then back to hot,....
Now I did a 2" plastic tube , vented my drives rear aux heat to my drivers side foot well. Makes a big difference with keeping the feet super warm on trips....

Re: A/c compressor
Ya, I'm not sure why they wanted the "aux heat" to mostly blow in to the back,
So, I removed my cover, and put duct tape over the two vent openings aiming back, put the cover back on, and found a flex/rubber tube with a decent opening, (I used 2" diameter) back/down opening to front foot area,(I think was like 2 ft, not to much tube needed) so now there is a decent amount of air the blows to the foot well
Now at least on those super cold days I can actually feel heat on the floor,. And still some heats going back from the passenger side, as the back always it hot.
This year I cut open the aux rear drives side down aiming vent hole so more air blows to my footwell,...
Come summer I remove the tube and tape for normal a/c usage
