1999 Chrysler 300m
|
|
|
Car has been running great until one morning I go to start it, it turns over and everything but the power windows and a/c & heater won't work. 15 minutes later, they simultaneously decide to start working. This has been the case for the past few months. IS NOT the alternator, what could it be? Any help would be appreciated! Thanks!

Im confused by the description.
"everything but the power windows and a/c & heater won't work"
Only the power windows and heater work? Or the power windows and heater wont work?

My apologies, I meant that as a figure of speech and now relies the dilemma it creates in the wording. What I mean was that everything works except the power windows and a/c & heater.

First thought is ign switch.... as both circuits are energized in start or run...
Suspect - Is the CEL on or do you have a remote starter ?

Surprisingly the CEL is not on although when I call for power on the power windows or a/c the dash defaults and the trac on/off lights up as well as the abs. Another thing to note, the lights illuminating the window function tabs dim whenever you call for power on the windows as well (for the first 15 or so minutes before they actually start to work).

Anything recently worked on or damaged on this car?

The obvious indicator would be that I had to jump start the car since it died in -16 degree weather other than that, nope

I would lean towards ignition switch as well. (NOT THE LOCK CYLINDER) There are several other circuits that I would think would be affected if the ignition switch is the problem. Does the transmission act any different when this is occurring? Does the airbag light and/or ABS light come on when this is occurring? Is the check engine light on?
Sorry missed that you mentioned some of those things.

Wiggling the key? It's a reoccurring problem and it doesn't involve starting the car. I'm thinking has something either to do with a bad ground (which I cleaned the main one), a bad relay, or bad cables???

I definitely don't and appreciate any advice given. I just immediately thought your advice to wiggle the key indicated you didn't fully understand the problem. I can assure you that wiggling the key has not done anything to fix the problem, thank you for the tip though.

As far as the transmission having any problems it doesn't. When the lights default on the dash, the air bag indicator does comes on initially as well as the ABS. CEL is not on. It really is quite the mystery.

Wiggling the key is kinda far out on changing anything with this, but free and easy to try.
You mentioned that the abs and trac lights come on if you try using windows or heater. At this point I would suspect ignition switch, but everything is a guess without testing. Are you going to be testing and repairing this yourself?

Wiggling the key itself isn't going to do much. You have to access the plug on the back of the switch. Don't blow this off because I had a Chrysler product the other day that cranked just fine but sometimes wouldn't start and when it wouldn't start the dash lights weren't powering and it turned out to be a switch that used multiple power feeds.

Re: 1999 Chrysler 300m

I thought so too as far as wiggling the key goes, and it definitely could have worked short term, but I am looking for a more long term solution. As a newly graduated college student I do plan on doing the repairs themselves. I've been at this for a month or so, thought it would be something like a bad battery, terminals or cables but it is abundantly apparent it is not. With regards to the ignition switch, would that explain why everything tends to work after about 15 minutes of running the car? I've heard theories of metal expansion (therefore more current flow) or the battery building up enough charge. Then again all the battery has to do is have enough charge to start the alternator and then it takes over right? Your help is sincerely appreciated.

The thing is Hammer Time, the Chrysler turns over flawlessly every time. It takes only a few cranks and turns over, so as far as that goes it's reliable. Could it still be what you are suggesting?

Hammer Time can you please explain how this could potentially be the issue? My dash lights do light up, and my car turns over fine and hence why I am confused but then again like you said I'm no professional. I appreciate your help.

Re: 1999 Chrysler 300m

Lets regroup.
the P/W and HVAC do not always get powered up at start.....
You recently had to jump the vehicle - dead battery - no problem before that.... Am I describing correctly so far?
> I asked about a remote starter ? before someone looks at a wiring diagram....
> I want to also ask - the CEL does it come on at every start @2seconds then go out?
> Jump started the car- no problem, crossed cables - key was in pocket or ignition Sw when attaching cables?
> Any chance you have a scanner - all code capable?
Stupid questions.... but there is a reason

Good plan!
You have everything correct. I don't have a remote starter and the CEL doesn't come on at all actually. When we attached the cables the key was in my hand and the last of your questions; I do have a scanner all codes capable and ran it and there was no fault code. I was hoping there would be, but assumed there wouldn't because of the CEL not being displayed.

No CEL bulb is functioning fine. There is nothing wrong with the CEL. I apologize if that was causing any confusion.

Re: 1999 Chrysler 300m

.....I am still thinking it is a key switch issue, I will look at a wiring diagram to be sure I did not miss anything ie everything going thru BCM or a relay...
Will think of a way to troubleshoot and confirm, some tests -

Re: 1999 Chrysler 300m

Hmmmmm...I took it to Shucks and had them run an unloaded and loaded test. Seems to be that the battery is fine but is being drained excessively. I cleaned the main ground but would the key switch also cause this problem? I don't believe it is the alternator as I had that tested too and it was running about 14v (barely okay they said). Another possibility I've been researching is a bad BCM which I'm hoping is not the case. What are your thoughts??

Re: 1999 Chrysler 300m

the battery drain is interesting- definitely look into thet... remember that there is a wait period for checking battery drains as modules go to sleep @30min would be a safe guess. Good tutorials on this drain checking procedure on UTube.
I mentioned the BCM as I am unsure if circuits utilize it, I will look at wiring schematic - time permitting - its snowing, not making for a busy evening.
PS as the issue is intermittent testing will be trickier than a hard failure.
