the 20amp fuse in the underhood box is good. Where are the pcm fuses located?

both fuses and bulb are good, I have to check the wire that is on the passenger side that comes off the glow plug wire next all I have to do is find were it might be located. I have no power at the 10amp fuse.

Turn the key on all I get is the glow plug relay clicking, Installed a new relay still clicks and no glow plug light, any help would be great. not sure were to start.

I think it was around $300.00

I used A+Auto Cooling Solution LLC for a complete rear A/C kit for my 95 burb work like a champ (877)606-8088

If you still have the 97 cooling mod I would be interested please pm with the price thanks:smile5:

thanks for all the insight I was able to put it on the machine today sucked it down made sure it held a vacuum for about an hour and serviced her up with 3.5lbs of R134A freon and ops checked good blowing icecubes out of the vents and the kids are complaining that it is to cold. (Perfect)

how much R134A freon does my 95 suburban hold? I serviced the freon today set the high side to 150psi and the low side to 30psi. I noticed that when I had the a/c on the compressor would cycle on and off, when I would turn on the a/c for the back passenger the compressor would not cycle on...

after more trouble shooting oil is only coming from the top of the dipstick the rest of the engine is clean as far as I can tell. Been all over it with a mirror and flash light.

I installed a new cranck case vent can about 500 miles ago. Do you think that is not operating properly.

I have an oil leak for sometime now and i'm starting to narrow it down, some back ground driver side valve cover starting leaking changed that with a cork gasket found that was not such a good idea. Removed that and changed with ultra gray rtv did this 3 times with the leak at the same place...
