Drivers side vent-hot Drivers side middle-hot Middle middle-cold Passenger middle-cold Passenger side vent-cold Tried relearn trick no change. I know there was something you had to do first so the actuator wouldn't spin out of control when you first put it on. Might try removing the battery connector for 10 minutes. Pretty easy thing to do, but now we have problems. There are 2 common causes for this. Silveradoguru, What did you find out? I bought another new resistor and wire harness this year and the original problem is there again position number 5 does not work. In other words, its like it does it whenever it wants to.
Any insight would be greatly appreciated. For those of you that have tried the fix in the video in the linked article, did it fix the problem? Outside temp would have nothing to do with it. I realize similar questions on this issue have been posted, but I needed some clarification on some points. Recently the drivers side started blowing air that was noticeably warmer than the passenger side, with both controls set on the coolest setting. Touch the red lead of your meter to the brown wire and check for a reading of battery voltage.
I found this to completely solve the problem for me. When I took it to the dealer, they said they couldn't find anything wrong with it. You could have low oil pressure caused by worn out bearings. On vehicles with this type of concern, it is usually caused by a malfunctioning blend door or blend door motor inside of the air conditioning system. Whenever it happened I would close the driver side vents, point the passenger vents in my direction as much as possible and role down the windows until I came to a stop light.
To do testing with a voltmeter at the harness connector you will need to test the following. After some time a burnt smell from the resistor unit started. It did fix itself by turning the truck off, waiting a few minutes, then restarting it. Actually, I prefer to wait 4 minutes because I remember reading that a few years ago and the extra time does not hurt anything. The only way to correct it was to turn the car off and back on and then it would immediately start blowing cold again. Only way to be sure is to have a scanner on it to control the door motor, and see if it moves. The computer may tell all of these electric doors to move all the way one direction.
If it's the drivers side then it's really easy to change out. Slide the new actuator into position, install the mounting screws and reconnect the wires. There may be some resistance if the actuator is at the full stop position. What I don't understand is it was working just fine, until I swapped batteries. Hello all, I am new to the forum. I removed the four 7 mm headed screws and pulled the panel out of the way. The passenger, and rear are working fine.
I wish I would have tried this! I had to change battery for other reasons but noticed after I disconnect batteries, 2 for diesel the air now worked in the front vents. Same goes to everyone else on here that have helped me in the past with my questions. Reconnect the battery and start the engine. Is this a simple inexpensive repair or a costly one left to the experts? I've seen several recalls 04-05's on this system but they said mine covered not in it. Any other suggestions besides possible icing? Sometimes the door actuator needs to be reset, as it gets confused.
Researched internet and found someone had removed actuator and open it up, cleaned grease off the contact and circuit board and it worked for them. If you can, the motor may be toast. It's underneath the passenger dash, where your feet go. Let's all complain and maybe they'll do a recall on this issue also. There is a temperature door motor for each side. Once the new actuator is in: Turn the temp control all the way to cold. Same thing happened on my 04 H2.
Passenger side blowing hot drivers side cold. Thanks in advance to anyone that is willing to help me diagnose the problem. While going back and forth from cold to hot on the drivers side climate control see if you can see that motor working should have the shaft that actuates the blend door sticking through it. Not sure if a dirty cabin filter can confuse the actuator sensor but my system now works perfectly. My truck has dual climate control. There are position marks on the back too.
Replacement of the motor would be needed. For example a door damper might be able to move to open, middle, or closed. I have read so much it's all overwhelming, any easy things to try or look for? The dark blue wire will have basically three different voltages that are important. At the time of this writing the aftermarket non dealer application books are incorrect. The control module would need to have a programming update done to it. This has gotten me by so far while living in Coastal South Carolina, Florida and Alabama. Sometimes randomly with the temperature set below 70 degrees and inside temperature much higher the Driver side will suddenly start blowing hot air while the passenger side will continue blowing cold air.
