Help to identify cut harness wiring - Hummer Forums - Enthusiast Forum for Hummer Owners


Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Maybe the GM dealer cut it when they did the heated windshield washer fluid delete. Who ever cut it did not do it right.

^yeah no kidding, pretty **** job.


Your best bet would be to put a test light on each wire and start flipping switches, turning dials, etc and see if any of the wires are hot. The harness looks factory but the tape, clips, and age but you'd have to test the wires and trace them back to their origination to see what they are really for.


If it were me, after completely testing them I would cut them back to the branches sections of the harness just to clean it up for eye appeal.

Yeah.... that would bug me. I'd be tracing it down to where it goes to determine exact what it is.

For what its worth, my 2003 does not have a ground wire attached to that bolt hole on the cylinder head there either. If that is stock then its something GM added after my year.

GM issued a recall to disconnect the windshield washer heater. They gave each customer $100 and disconnected the system. I had my local dealer do it to my 2006 LE. I asked them not to cut any wires. I got my $100 and then I found the company that makes the heated washer fluid systems and bought their redesigned kit and installed it on my H2.
While I rarely use it, I do like the fact that it functions like intended.

Thanks . Then the dealer cut it while I got the truck for repairs
Is the windshieldheather switch on the left next to the wheel?
I got a button there which isn't connected.
Fortunately is nothing to worry then

Alphatherm is the company that makes the kit. I think you would like it.

AlphaThem has developed a universal heated wash unit, called the AT-37GM, that replaces the production GM unit.
The AT-37GM is AlphaTherm’s latest generation heated wash unit that will plug into GM vehicles without any necessary
modification. This plug and play unit, can be easily installed by yourself or by any repair shop in 15 minutes or less.
The AT-37GM exceeds the requirements of the original GM heated wash.
The module contains a higher quality plastic material, rubber seal around main cover, silicone coated electrical terminals,
new printed circuit board design with electrical circuitry rated two times higher than the original GM heated washer unit,
allowing the unit to survive a much harsher electrical environment.
