New to the forum so "Hello" everyone....

My 2003 has been acting up.........

1. Speedo would stick at various speeds when car is shut off, Then next start would begin counting from that speed then each consectutive start would begin to read from a lower speed ( Example: would shut off car and speedo would be stuck sitting there reading say 50mph. Next time would drive car and 10mph would read 60, 20 reads 70, etc. Shut car off and speedo would lower to read say 35. Go out for drive 10mph would read 45, 20 reads 55, etc. Then couple drives later would finally make it'* way back to 0 and would be fine. Did this twice now in last 6 months or so. Presently OK.

2. (This is the main reason i'm here on this forum) Driver'* door control panel not responding. No windows, door locks, mirrors, nothing. Door lock will function using key fob. Other door'* controls are fine. From reading threads here I checked battery connections. Totally clean. Took off cleaned anyway, reconnected (to "reset" electrical system) No improvement. Looked at both fuse/relay blocks all looks fine. No sign of water damage under back seat. Took driver'* side kickboard off to inspect harness and ground buss. All looks as day it came out of factory. No sign of water damage so didn't cut into harness assy to actually see ground buss but have no reason to suspect internal problem. (No sunroof BTW) Haven't checked passenger side yet. And haven't gone into driver'* side door yet where people have mentioned a module to inspect. (Most likely suspect??)

3. (And of all I read here this one might be a first) I can disengage my cruise control while driving by signaling left or right. (NO, SERIOUSLY )

So far the other gremlins you guys have discribed have yet to find my vehicle.

18 views and no suggestions??

I pulled my door interior door off today. Everything "looks" fine. No signs of water damage or wiring issues. I pulled off each connector to my door module and reseated hoping for a small miracle. No improvement getting my door locks and windows to work. Does anyone have the procedure to check this module to find out if it'* bad or the problem is up steam?? I assume i'm looking in the right direction for this fix. If not let me know of other things to look at.

Here'* a pic of the DDM:



....and does anyone know what this component is and does?? It'* behind the driver'* side kick panel. And I noticed one just like it under the driver'* side back seat.



Thanks for any & all help............

Purplehaizer might be able to shed some light on this, more his area. But it sounds to me like a short or grounding problem. These can be a major bear to track down.

The DDM'* do go bad. Unfortunately you typically need a Tech II (dealer testing tool) to know for sure.

Sorry for the forum "foo-pah" but there were no responses on this thread to be missing any information from.....still isn't........

I'm wondering if the key here is the "missing" grounds on other connectors. There should be no reason to be missing ground connections at anytime. Correct??

It'* really not a big deal. Others have started a thread before and it'* simply better/easier overall for folks searching to see one thread with everything.

You shouldn't be missing any grounds. The 00+ ground packs are pretty solid and don't appear to corrode etc like the earlier models.

I'm missing grounds on some of the other connectors. I guess i'll have to trace them upstream to find out why. I don't have a better plan but I need my door controls back ASAP.

Thanks for all the input guys.........

more information = more input

Bill suggested you get a scan done from someone with a Tech II scanner (usually dealer). That'* a good first step. Electrical problems are difficult to diagnose when the car is in front of you and you have an electrical test meter, let alone trying to do it over the internet with only sketchy information.

We can walk you through the steps to a solution, but you have to follow the steps.
