Having problems with your 2003 Hummer H2 ?

Electrical malfunctions.leaks,and suspension pump problem 2003H2

\015 I have water pouring in from interior lights, my windshield wipers come on and do not shut off..disconnnected a fuse and now they make a horrible noise but turn on and off, my suspension pump has a mind of its own and really acts up when it rains. It will not ever jack up and is in the total down level so hard to drive it bouces..or if it does work it will not turn off and will run the battery down. I have taken it to 2 different dealerships and nobody can figure out what is wrong!!! Had a manual toggle switch put in to turn on and off but still pumps only when it wants to!! This Hummer is posessed...HELP!!\015 Posted / edited by AnonymousUser on : 13-07-2020

Water likes tru the overhead lamps change all the sills
Sounds like wires melted together and when ever one wire gets power it powers whatever else that wire is touching look for stuff like that. which makes sense because wiring problems are a pain in the a## to find some times.
