Success & a Procedure if you want it

Year: 2004
Make: Chev
Model: S10 Blazer
Engine Size: 4.3L
Refrigerant Type: R134
Ambient Temp: na
Pressure Low: na
Pressure High: na
Country of Origin: United States

Celebrating a bit here. I replaced the compressor, accumulator, and OT for my 2004 S10 Blazer today. Was doing this as a result of a failed clutch. All went great, and results were fine too. Only hitch I had was that the compressor HP cutoff switch that I got was not a type that would mate with the electrical connector on my Blazer. The connector on my Blazer has a round insulator (like on the accumulator LP switch) and the HP cutout switch I received had an oval insulator. So, I re-used the switch from the old compressor. I am very happy with the results.

I had written somewhat of a procedure to use for the job, including the re-charge to keep me straight. Kinda comes as natural since my work is related to instrumentation and control modifications to nuclear power plants. Thought I would upload it and make it available for others to use. You can use it as-is for 2004 S10 Blazers or modify it for other vehicles. Only problem is that I have not figured out how I can upload it. I don't have an FTP site presently in which to place the Word file. Can anyone help with that or tell me how I can make it available? I could cut-n-paste it into a message here; however, it is four pages long.

Thanks for the help on the forum with some questions I had. I need to also make AMA aware of the possibility of a boo-boo in their recommended parts listing with the compressor HP cutout switch since there appears to be two possible switches in use.

You can e-mail it to Tim ( and ask if it is a complete and appropriate procedure to post on the "Automotive Air Conditioning Procedure" page.

Feel free to post it. As with anything written on a forum. One needs to use the information as a guide!
