Intermittent door issues
Every once in a while my doors won't open. The window indexes, but the door won't open, I have to go in the trunk. It's both doors. I tried cleaning the contacts in the touch pads, and the car battery is new. I'm thinking the fact that the windows index mean it's getting a signal. So I would think actuator, but it's both doors when it doesn't work, and they both work when they do. So I'm kind of confused and looking for advice. Thanks

Yes, this is an odd one...I see you are a mechanic so you should have access to a factory level scan tool...I would check the inputs to each door to see where your problem may be...any DTC's ??

I went to hook up my scanner and the door wouldn't open, had to go through the trunk again. Did an all module scan and found some historic codes. I deleted them, we'll see if they come back. After closing the door it works fine again. Here's the codes I found:
drivers door module:
B1420- control module voltage
U1017- lost comms with ecm
U1153- lost comms with hvac control module
drivers door switch:
B1327- supply voltage circuit low voltage
passenger door module:
Same as drivers door

I had issues with mine recently, tried cleaning up the pads, switched driver and passenger side. Ordered a new door actuator and getting it put in on Monday and hopefully it will work again.
