Default 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 ??

Well, I'm not an auto mechanic. I do have an ok scan tool. There's no lights on, but maybe I should scan the body modules to see if anything shows up

If you have a scan tool to look at all modules that would help...code readers normally only read Powertrain 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.

I recommend charging battery.
Or if over 3 years old R&R battery.
I know when my battery is charged doors open great, when battery is low from heat soaked stop and go multiple engine start/stop cycles my doors have had
issues.

I just put a new battery in the car when I took it out of storage, which was about a week before I started this thread.

It has now been a few weeks since it's given me a problem, so I'm just waiting for it to act up again

I ended up getting the rebuilt OEM door actuator off ebay and had a shop put it in for $150. Problem solved on mine.

If it was only the 1 door acting up I would definitely be leaving towards actuator. But the fact that both don't work has me questioning

Have you checked and cleaned up any of the grounds? I know if they are dirty they can cause all kinds of weird issues.

I cleaned the pads, I did not clean grounds. Do you know where the ground points are for them?

By looking at your DTC's you probably don't have a ground issue...you have some communication as well as low voltage ones...you said you are not a mechanic so I'm 99.99% sure you will not be able to diagnose this especially if the extent of your abilities is just cleaning grounds and not testing...seek out an auto electric shop in your area.
