going to replace my ac compressor.....question is ...has anyone removed the compressor out of the bottom underneath the truck or will it only come out the top.....i'd rather not disconnect the water lines if i can avoid that.....just asking what other have done here when replacing

thanks!!

I've been told the compressor can be removed from underneath and no need to remove the radiator hoses, however on my 05 I simply just couldn't get it out, perhaps I missed a trick.

 

According to Mitchell / GM it does not require the removal of coolant hoses nor water pump

oceanbrave...i watched the youtube video you made.....if i might ask....what were your ac issues?.....was it not cooling at all?.....or just not cooling well? when you made the video

 

jhall there was no cooling it was always blowing air just above ambient, the high-side low-side pressures were the same. I tried re-gassing but to no avail, pressures remained the same and of course no cooling.

The compressor clutch/belt started to smoke so I had to turn-off the A/C.

It turned out the clutch mechanism was shot, think the compressor must have had seized at one point probably from debris in the system.

No one here in the UK wanted to touch a Hummer so I was forced do job myself, my biggest mistake was buying cheap spares, particularly the condenser which leaked.

 

Neal.....do you by chance have that procedure you could email me.....not sure how it's going to come out the bottom but i could be missing something

thanks

Hummerz got it,

thank you!!!

 

i can verify that Hummerz directions are spot on....took the fan shroud off and compressor comes right out without issue!!!
