I came home, shut the car off today and something under the hood was still running. Popped the hood and it was what I think is the Air Pump was running & hot (drivers fenderwell). I unplugged it to get it to stop. waited about 20 minutes , plugged it back in and it is still running. Started the car rev'ed it up a few times, held it @ 2,500 RPM for 20 seconds or so, shut her down & it's still running.
Anybody ever have this problem?

 

Contactor must be welded stuck in the RCM. There is a good tutorial on here on how to clean the relays.

 

Welded or spring broke in a contact was what my thoughts were or getting a constant signal to run from the ECU or controllor.
Just hoping someone else had the same problem so I know were to start looking or what to expect on repairs.

 

Steve, I think DJ worked on his....look for the thread...I'm on the road, or I would look for it...but, I believe he cleaned his ......

 

If the contacts are not too badly pitted they can be cleaned up....if they are pitted badly it will work but continue to happen as they continue to pit worse..... sooner or later you will have to replace the RCM..

 

Humm, this SRT-6 is the one I just bought from Jeff Cobb. It had the extended Maxi-Care warranty that I transfered for $50 the day after I brought it home. But it has a $100 deductable on any repairs.
I wonder if I should just take it in & let Chrysler replace the RCM. Mike, do you know if it is an open contact or a little enclosed relay. I've not had a chance to look at it at all, other than unplugging it. I figured I would locate the relay & meter it out to see if it was stuck closed. And I didn't know if it was a small control module that was sealed & would need replaced.
Thanks, Steve

 

15 minute fix. Remove RCM module, pry open box, clean obvious culprit relay with point file or emerycloth, reassemble, drive car. Done.

I'm guessing you've been there/done that? That would beat paying $100 deductable @ Chrysler. I probably should look into what a new RCM module cost in case I need to replace it.

I gotta ask with a screen name like tunaglove, are you a freelance gynecologist?

 

Yes I Am!:d

 

or switching one RCM from car to the other. You do own 2 right?

 

Yep, could do that. The modded/blinged up low milage one probably isn't leaving the garage again till spring.

 

Steve,
As noted, you can access the contacts. If you have the MaxCare, I would let them replace the RCM...$100 is cheaper than the RCM price... but free is a good price too, if cleaning the contacts does it for you...

You could do the swap first and confirm the diagnosis.. then take it in...

 

I might pull it out and take a look at it, I done some searching & there have been a lot of problems with the RCM's. But mainly no start issues & cracked solder joints, but also could be an O2 sensor problem too. I may pull the one out of my other as you said to confirm thats where "run all the time" problem is. I have a feeling though that it's going to the dealership & I'll just do the $100 and also have them look at a possible powersteering leak. There is no heavy dripping or leakage, but I can smell it and everything down in that area has a slightly moist build up. Unless they want to charge me $200 for two different problems.

 

Does he have the dual cai on it?

 

SL55 intake.....

 

The one I bought new has the SL55 on it. The one thats having the air pump running problem even with the key off that I bought from Jeff Cobb has a single NeedsWings intake on it. I'll probably pull the RCM in the next day or two, I'm sure that the contacts are probably stuck on the relay.

 

when people install the dual cai, there is a kit for moving the power steering lines...just thought maybe this had been done...sometimes they don't get the lines on quite right, or tightened correctly...but, it has a single, so never mind....hope it works out for you...I was down your way a few days ago...

 

If you know what you are doing, you can remove the faulty relay and replace it. These will be common relays and the cost of one, est. $15-$30, will be cheap compared to the whole board.
You just have to master de-soldering, how hard can it be?

 

Believe this is what you are up against.



Sounds like the contacts stuck together.

If I could get folks to send me their bad RCM's I could start switching out the Air Pump relay with other relays on the RCM.

 

if mine ever goes bad i will be glad to send it to you dj!!!
