h24us:
Sorry to hear about your trouble. You would think the H2 dealer would be the MOST knowledgeable person about AC in a place like Las Vegas where keeping your car cool is critical. Unfortunately, AC sometimes seems to be a weakness of the H2 based on other posts I've seen. I'm thinking about installing Flex-A-Lite dual 19" electric fans that come attached to a shroud that exactly fits the brackets on the H2 radiator. I am told this solves the problem. I've heard it also improves gas mileage about 1 mpg by decreasing drag on the engine by about 17 hp.
A cheaper solution might be to buy a replacement fan that has flexible blades attached to the vanes. At low speed, the blades have a sharp angle of attack and move alot of air past the radiator/condensor. At higher speed the flexible blades flatten out and let the air pressure in front of the moving vehicle do the job. I installed a system like this on my car about 35 years ago when I had an overheating 396 Chevy and it solved the problem. Don't know if it would work for you, but I don't believe it would be too expensive to give it a try.
Don't know whether GM would give you warranty grief if you make any of these changes.
There are other people on this forum who know alot more than I do. Maybe some of them will weigh in.
Good luck,
George SSSS
