I have a 2005 hummer H2 and the ac blows cold out of the driver side and very hot out of the passenger side vents. The rear also blows cold. This was barley noticable last week. I had the battery go dear. onece I replaced the battery, the passenger side blows very hot. Is there a blend door reset or fail safe that has the doors in the hot position?

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.

SOURCE: AC BLOWER FAN STAYS ON

When does it go off (the fan). I assume it does, sooner or later, go off? Some blowers (high-end vehicles) stay on a little longer to clear moisture, but if this just started (hasn't happened since day one) then I would assume it is a short (pray it isn't) or the blower cutoff relay/blower motor relay. If neither relay is available for that car, it could be built-in to the motor. Then, try to unhook the motor and put a tester on the connection plug going into the motor and see if you can get power with the car on, and watch it disappear once the car is turned off, that indicates it is the motor or the resistor atop the motor.

Hey I have the same problem, but only when it rains, it comes from the sunroof then leaks into the carpet.

SOURCE: 2005 h2 wipers run all the time

There was a recall on the suv`s but I`m not sure the h2`s were included.The fix was the replacement of the wiper motor module which is on the motor.All you have to do is remove the cover on the wiper motor and the module is there.Just unplug it and pry it out with a small screw driver.You can get a module from the dealership parts department.Just follow the directions.Hope this helps.Good luck.
