My 2003 hummer h2 is leaking on passenger side. I

Do you get heat? If not its the heater core. The core is blocked with caulk. You can either attempt to remove the blockage with a transfusion/ liquid transfer machine or replace the core.

They are not vac on the h2. there is 2 for temp control, one for recirc and one for blend. check the hummer forum as there is a great read for it there. the driver side actuator is really ez as it's under the glovebox, 20 min fix. the rest take removing the whole dash but it's not that tough.

to get your part for your H2 follow this link below http://www.ebay.com/sch/i.html?_nkw=2005+Hummer+H2+passenger+side+mirror+&_cqr=true&_nkwusc=2005+Hummer+H2+passengr+side+mirror&_rdc=1

replace air bags.200 bucks a piece, olny takes bout twenty minutes

first is the water coming in while the a/c is running,because your evaporator might be clooged.if the passenger floor is wet thats a sign that it may be

check your fuse box for blown fuses and check the wiring going into the door and see if it got pinched wires

Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

THIS HAPEN TO MY H2 I REMPLECE THE UNIT IF TAKING THE BATTERY DID'T RESTAR THIS UNIT THEN YOU HAVE TO REMPLACED UNIT

never worked on a hummer but rule of the day is that there always is a drain on the firewall on the engine side. usually a small rubber hose about two inches long direced downward. Usually you can stick your finger in there and clear it out. Don't shove anything hard into it or you can punch a hole in the evaporator core.

had d same problem , check your rubber seal between door hinges and the body .
