Howdy folks.

So I get in the car this morning and I notice it starts a little harder than normal. (It usually never skips a beat, this morning it stumbled just slightly). No big deal but then...

I notice the gauges aren't working. The only light on the dash is "Check Engine".

So I shut it off, turn the key to run and the gauge cluster comes alive as usual, so I start the car, put it in R and about halfway down my driveway, the gauges go again.

I'm running late for work so I forge ahead without the gauges and notice some other funny stuff... blinkers don't work, AC won't blow cold, trans is shifting weird (pulling away from a stop is sluggish), the steering is lighter too.

I've since shut down/started the car half a dozen times and it's the same: gauges come on briefly then shortly after starting, they shut down along with everything else.

I'm going to pull the battery cable when I get home from work and also see if I can get my scanner on... but in the meantime, anyone experience anything similar?

I can't help you with how to fix it, but that sounds like your CEM might be going- did you lose power windows or the sunroof?

Pull the CEM fuse, wait a moment, put it back in. CEM resets and stuff works again. It's worth a shot- something similar happened to me and I was able to fix the symptoms by pulling the CEM fuse. Doesn't address the cause but it can work.

Thanks for the response... Sunroof and windows still work.

I'll try the fuse pull first (I can do that in the parking lot before I leave ;) )

FIRST thing you'll want to do is have a deep battery check, and a super look at the alternator.
Mine did this on the road once, and it was 105 degrees: Everything lit up all at once, and then systems started shutting down. NOTHING was working, and then it began to get hot - I stopped immediately and threw the hood open.
Turned out it was the alternator, and heat killed it finally. Has yours ever been replaced? Cost me a grand.

Alternator? I have no idea. I bought it used and have only put about 10K miles on it.

I'll have it tested. The battery is newer (under 2 years) but if the alternator is toast, who knows what state the battery is in.

Pulling the CEM fuse sorted it out for now.

It's about 100F in the shade today and I did notice the blower fan was slowing down when I come to a stop and the engine is idling.

So the alternator (or voltage regulator) is probably on its way out.

Thanks for the suggestions, all.

W....T.....F!? A grand for an alternator. And it’s probably a pain in the ass to replace too huh?
