05 suburban 2500 driver door switch panel not working

[xxdunker]

05 suburban I'm having an issue with my driver door. Window switch isn't working at all. No windows, locks, or mirror adjuster. Doesn't lock or unlock from the remote either

I know normally there's a broken wire in the door jam but all my wires are good. I checked them all last week and they all have continuity from the fuse block to the connector at the switch.

I haven't been able to find a good wiring diagram but I know I'm getting power and ground from the fuse block.

I do have power in the door to the speaker and to the mirror turn signal. (2500 tow mirrors with signal inside)

Today I got a new to me switch panel thinking the panel is bad but still no luck.

The only thing I recently did was replace the door lock actuator. Not sure if this could cause the issue but I did that about a month ago and it was working fine at first

Anyone able to help me out with this I would really appreciate it

I have a wiring diagram for a 2004 suburban on my office laptop. I can look tomorrow.

Maybe you got a bad switch replacement? It was used? It seems to me these switches act up if you leave the window open and then it rains. It's happened to me before more than once. You can pop the cover of the switch and clean the contacts.

I would appreciate it. Cleaned my original switch and didn't have any luck. Got the switch from a friend that pulled it out of a parts truck. Was working before he pulled it as far as he says.

Dumb question: Have you checked your fuses? I think the switches are on different fuses than the turn signals. Note: I don't know for sure -- I don't have a wiring diagram, and I won't get out to my truck for a bit.

Checked fuses last week. I plan on re-checking them again in case I missed that. But I don't think that's the issue I have power from the fuse block connector

Don't quote me on this, but I've heard that some trucks need this switch programmed in order to work properly. Especially if you have power folding mirrors. Something to do with the fact that it's technically not just a switch, but it's actually a computer module (the actual name is the "Drivers Door Module" or DDM) and it needs to be properly programmed to the VIN any time it's replaced, or parts that connect to it such as a window motor or lock motor are replaced.
Someone please correct me if I'm wrong, but that's what I heard a few years back when I was helping a friend upgrade his 03 to power folding mirrors.

A used DDM from a like-optioned similar year (in your case, probably '05-'06) should plug-n-play. If it's a new switch, it may need to be programmed.

Pics of both switches (the tops) side by side? Are the part numbers the same?

I've heard that as well but also if the part is from a truck with similar or the same options it should be plug and play. Worst case I used to be a GM tech so I can always go back and use a tech 2 or gds to program it

Going to double check part numbers in the AM but I believe they should be the same. Donor part came out of an 04 suburban

I added powerfold mirrors to my 03 using parts from different donor trucks. Never had to get anything programmed, everything was plug n play.
OP--If you have folding power mirrors that replacement mirror switch would be wrong, it won't work for you. But that would just affect your mirrors from folding nothing else.

No folding mirrors just basic 2500 mirrors with turn signals. Not even power adjust

Did you figure it out?

I looked at my project 04 suburban 2500 yesterday. I had forgotten that I had popped in a switch I got from a 2004 Yukon XL that was getting parted out and got an engine from. The switch didn't work at all either.

I reinstalled the original switch and it works, except it doesn't lock. I can lock from the key fob, but not from the door switch. Everything else works though. There is board inside that has some sort of chip.

Been playing around with no luck still. Went over to Chevy and was able to uss a mdi2 and programming software to try and reprogram my driver door module (switch panel) and wasn't able to do it. The module has no connection and doesn't show and data and can't be programmed. Tried to put a jumper wire in place to the brown signal wire but still no luck. Any help is appreciated

We had a similar issue with our '05 Suburban 2500 LT; it was bad wiring to the ECU under the hood. Some were rusted, some were rusted through. You might want to look there. Couldn't hurt.

I had similar issue.
step1 remove from door
step2 disassemble module
step3 clean with rubbing alcohol
step4 dry
step5 re-assemble module
step6 re-install

(only works about 3/5 of the time)
