Why do we not see DTCs in the 9XXX range?
Take it to a dealer if necessary, pay the money and learn the possible problem.

 

It might be an easy fix but certainly the least aggravating way to deal with it is to just junk it.

Is it a manual? Got a clean title? Maybe I could get it hauled off for you.

 

Probably so.. "double tap" and hold.. raise or lower to desired position and release... I'm gonna guess if you hit it a 3rd time your windows would stop.. ?

 

and your guess would be correct

 

and when u doub le tap and hold, what does this tell me ,go see a Chrysler or Mercedes shop and tell them what? 😂

 

???? Is it time...

If the windows are working as described.. TCM is sending signal to BCM for window control .. failure to lower when turning the "D" handle seems to strongly point to the switch in the header at this point..

"Note:" I'm not an electronics engineer.. nor did I sleep at Holiday Inn last night..

DIY testing option.. pull yours and test switch for continuity ..

 

We can give it a try, thank you. RB

 

Just hit the top switch with 2 taps, holding down the second tap and the windows go up and also down on the second hold. Looks as if the windshield header switch is the source, everyone in agreement? Thanks RB

 

I am in agreement. Switch, adjustment, wiring, PTCM module.
What's a REB doing out on the left coast anyway ?

 

you've heard of ham fisted mechanics, well ...it was supposed to be Red ... nuff said😁

 

Jawohl Herr Richtofen

 

In regards to "D-ring release won't lower windows" it might not be the header switch.

If you have skinny fingers you can activate the header switch by hand without disassembly. On my car the switch works fine but the D-ring doesn't lower windows and I have all sorts of other issues. "Windshield header switch" is a common broken-record response on this forum but I have never seen any evidence of one actually failing, being replaced, and fixing top problems. Not a single time.

 

Great news! You can manually activate or deactivate the switch (is pushed in closing the circuit or opening it?) Which achieves nothing other than the switch is still there.. Does manually pushing it tell you if the circuit component (contacts) are not broke or corroded?

 

Well, I sorta feel the same way and going in to a Chrysler store that was on my rounds several years ago when gainfully employed with DiamlerChrysler.Other than an OBD2, is there a seperate device to diagnose the top faults? Thanks, RB

 

Second thought.. maybe you are correct.. should we just advise purchase a new PTCM? No sense in chasing and checking the little things first right? SMDH

 

Yes. On my car I can activate/deactivate the warning beep/LED by pressing and releasing the windshield header switch. Continuity can also be measured without disassembly.

 

You OBVIOUSLY found the problem, based on what we discussed on the phone and what you told me in your last text:

• Turning the D handle does not result in the windows going down.
• ALL OTHER functions of the top system work fine.

Given those two points, what else could it be? This has to the the simplest, clearest electrical issue you could have. Replace the switch and be done with it.

Of course, the problem is finding a new switch. I've never actually seen the switch itself, given that it is hidden. I suspect MCM Electronics or Digikey has a switch that could be used, but first you must have the bad one in hand in order to identify what you need.

I suppose one could grab one from a junked car at a salvage yard.

 

 

MCM has those, but I cant tell - is the phillips screw all that holds the switch in?
