SOURCE: 2004 hummer h2 leaks water from roof over front

Seal all the lights on top. Mine flooded from the water running down the light harness wires. Used clear rtv sealant and fixed it. You will have to remove the seal the two larger lights on the corners.

Where is the map sensor on an h2 hummer


The only sensor on this truck called a MAP is the fuel vapor pressure senor and it is on the fuel tank. Are you sure you don't mean the MAF sensor, it is located in the air intake to the engine.. See picture below. It would help if you had a fault code for the problem. If Autozone or another free scan told you this is the part that is defective ignore them, they are not trained techs and would just love to sell you parts that may not fix the problem, its not their money after all.
