Car won't start - windshield wipers going crazy

[kilo3031]

I was told that the problem had been fixed yesterday. The service tech was not able to tell me what module(s) was replaced, but said that they are also replacing the ignition as a precaution. Why would they need to replace the ignition if they 'fixed' the problem?

Today I am told the problem is still happening. Its going to be 2 weeks now that the problem appeared. It was only working for 5 days.

Hopefully, the dealer is talking about the ignition lock solenoid (10391401). Partsguy is correct on the ignition switch assembly.

The vehicle was at a non-hummer dealer for 3 1/2 days. Its been at the hummer dealer since. Almost 5 weeks total.

I don't have time to make up stories and really this has taken to much of my time. I don't have time to call this dealer everyday. So whether you believe it or not, this is the case.

I started having trouble with my H3 about 5 days after purchasing the vehicle. Up to the point, I was completely satisfied with the vehicle.

The problem started when I switched my lights from auto to parking lights. This caused the engine to turn off. When I tried to turn the vehicle on, the windshield wipers starting going crazy and the engine would not turn. A light appeared on my dash (the light with a vehicle symbol with a lock in front of it).

The problem happened at a camp location 270 miles away from my home at midnight. I called onstar and they did not see any problems. I had to have my vehicle pulled to the campsite.

I tried turning on the vehicle an hour later and it turned on fine, no problem. I was able to ride the vehicle all day the next day, but the problem returned in the late afternoon. I left the car parked there and again was able to turn on the vehicle the next day.

When the problem happened again, I found that I was able to turn on the vehicle by turning off the exterior lights. As soon as I operated the windshield wipers or headlights, the vehicle would shut off (even during motion).

The next day I had the problem all day but was able to get home before it got dark (had to hurry because lights no longer come on without causing engine to shut off)

My vehicle has been sitting at the dealer going on its fourth day and they are baffled. No fix seems near.

What should I do? Can I make the dealer give me a new vehicle? Vehicle has been non-functional longer than I had it running normally. </div></BLOCKQUOTE>


Crazy question dude ,bare with me.Have you washed your vehicle before this using a high pressure spayer.

Sorry to tell you, but it sounds like the dealership tech mis-diagnosed the problem.
They replaced the PCM, yet it could not cause the problems you mention (other than a no start), and usually a failed PCM will not damage a BCM.
The BCM if it fails can cause all the problems you mentioned, as well as a no start, since the BCM gives the OK to the PCM to allow the injectors to operate (part of the anti-theft feature, called PASSLOCK).
There is no ignition module. Therefore, I would bet the PCM was never at fault, and the BCM should have been replaced from day one.
Again, these are my thoughts, and it is hard to diagnose a problem when the problem is not in front of you.
However, all indications point to a technician who did something wrong.
I would demand that the dealer called the GM Warranty Parts Center (WPC) and tell them to get a BCM out to you...NOW.

I ended up giving up on the dealer that had my h3 for 4 days. I didn't take it to the original dealer I purchased from because it was located about 60 miles away.

I called the service manager before I took it to him and he gave me a better game plan than what these other guys were doing. I hope to see some results tomorrow.

The car was really acting up for them.

I also agree that the BCM should be the culprit. I also suggested they replace it. They claim that they checked with their computer and it should be fine.

I'll keep everybody posted.

WORST DEALER EVER!!!!

My Vehicle is still not fixed. I have been told it was the BCM they were waiting for and then the Ignition switch. Now we are back to BCM. Either way, the part isn't there!!

All GM and the Dealer know is that its on a truck between here and Michigan.

The Dealer has not made any effort to keep me updated. It isn't even guaranteed that this is going to fix my problem.

GM told me the part was supposed to get there on Monday.

This all sounds like BS. If it's not BS you're a dumbass for not taking it to a Hummer dealer for the warranty work, regardless of how bad traffic is or how far away it is.

First, you crank a vehicle. You don't "turn it on." You would drive it, not ride it. The engine dies not "turns off."

Then there all of the inconsistencies with the dealers among numerous others that are too many to list.

3 out of 10

I was just told that the PCM was the one that was replaced. I am now told that the BCM needs to be replaced, but that this part is nationally out of stock. GM is closed for Thanksgiving and they won’t have a status till next Monday.

Looks like I’m looking at least another week. </div></BLOCKQUOTE>

Kilo , fstop is correct I am having similiar issues with my H3 about not being able to start.Mine has been in the shop since last Wednesday and they are still waiting on the BCM module to be delivered.They told me it was on backoreder.I think they should pull one out of an H3 on the lot and fix mine.

The module that controls the ignition is called the BCM. The BCM also controls the lights, the washers, and about everything else.
First Hummer asked if you had marker lamps...do you?
The BCM is in a pretty water tight area, and unless there is some leakage somewhere else, like mis-installed marker lamps, it should stay dry.
Most important thing is if there is a water leak, tell the dealer not to just replace the BCM, but to locate and repair the water leak. If not, you will be back again.
The H3 is designed to be as water tight as possible. If you don't have marker lamps, there could be a problem; as any man-made object can have.
Important thing is to get the dealer to fix the water leak...that is if it was really due to a water leak. Possibly, the dealer can't tell and just automatically blamed it on water.
Some dealers believe they have to blame it on something, rather than admit that it was due to something they can't explain. A BCM can go bad on its own, not a real problem, but again, man-made.

I have gone through deeper water, at a faster speed, and no problems here.

Sounds like a defective cluster and probably the same problems that other have had on this thread.
All I could recommend is a trip to the dealer.

[f5fstop]

BCM is not VIN specific, until it is programmed into the vehicle. So, I don't see why they couldn't ship one from the plant.
Switching between two cars may or may not be possible. Not sure, but I do know some GM vehicles can't be swapped due to being VIN specific, and once tied to a VIN, they cannot be switched to another vehicle.
They can be returned and rebuilt by Motorola, Bosch, whoever manufactured it, and then it is like new...no tie to a VIN.
