Hello to all,I had my 2003 hummer h2 acting funny for the past year many of the dash light would come on and blink for no reasons like if it was hunted, also I had water coming in and was soaking my drivers side carpet, then my air bag light came on, took it to the shop they wanted $550.00 to fix it, didn't repair it was going to wait, after about 4 months truck kept on acting funny, one got in and turned the truck on then I get UNKNOWN DRIVER come across the dash and my power windows wouldn't work radio, gas gauge, temperature gauge for radiator more trans would work, battery light and abs light would stay on, SO... I took it to the shop again and apparently the air bag module wasn't allowing all the other modules communicate properly and just stop working, the whole thing to repair was $1150.00 truck is working fine now

 

Took my 05 H2 in to local GM dealer as well as independent shop both said I needed the specific unit and that it was NLA. Called GM help and they could not help. If I can find a replacement I'll let you know.

If you hear of anyone with the same issue encourage them to fill out a complaint with the DOT that way GM may take a look at it.
