Hot air comes from drivers side only for minute or two then stops

Just to confirm the issue so that we are on the same page, the driver side blows hot air when you have it set on cold? Or is it the passenger side that is blowing hot when set on cold?

It sounds like the actuator is the issue but I just want to be sure I understand the issue so that we are giving the best advice.

Please review this material and let me know if I am not understanding the issue.

Sir,good evening.When the heater is turned "ON" only passenger side blows hot air.

1. I replaced the broken M2/15 actuator arm.
2. I changed the M2/6 actuator.
3.I then synchronized the M2/6 actuator by pressing the defrost and re-cir.switch simultaneously.(it stopped fluctuating,lastly only defrost lamp stayed lit.)
4. I got hot air during the synchronizing process through all the vents, but, now no hot air from drivers side while passenger side I do get hot air.

I noticed that there is no movement of the M2/6 actuator lever.
Is it something to do with the synchronizing procedure.Your valuable advice will be highly appreciated.

If the actuator is working when you run through the sync process then we can assume that the actuator and wiring is okay. This would leave a module issue.

However, we need to test the wiring just to make sure you are getting the 12volts that you are supposed too and then the signal wire should vary depending on the position and you can compare this with the passenger side that is working.

I attached the wiring diagram that will help with this.

Please run through this and if the voltage is the same on both blend doors then you need to replace the control module. Thanks

I will proceed with , as you have suggested and let you know the outcome .Thanks a lot Sir.

You are welcome. Please let us know what you find as I am curious about this one. Thanks

Sure,I will.Thanks Sir once again.
