Well, I removed the driver's seat and put the top down to allow more room to get at the BCM. I was able to remove both the back (towards the Rear) two (2) nuts and the front (towards the hood) lower nut. I am having fits trying to get at the front upper nut. Perhaps someone that has removed the BCM can give me a hint on how they got at that upper front nut to allow removal. Again, I appreciate all of the help and suggestions I have received.

Regards,

Thanks for your input, I have ordered a flexible extension for my 1/4" socket drive and I will try and get at the nut with the extension. Did you have to lay on your back to get at the nut or were you able to get at it without doing that?
I appreciate the information and I am hoping I can get the darn nut off. I told my Wife that if I have to get on my back she will have to get help to get me out of the car.

Thanks for your reply, I did lay on my right side and was able to remove the BCM. I just cleaned the connections in the BCM and the Plugs. I am taking a break and will put the dielectric grease on the plugs in a little while after my body returns to normal. You were right it is not comfy.

I will let you know if all this solved the problem when I am finished. Kind of funny in that I did not think I was going to be able to get out but I managed to do that.

Removed the BCM, used contact cleaner on the BCM connections and the three (3) plugs, put dielectric grease on the plug connections using a makeup brush, put everything back together and it did not solve the problem. I guess I will sell the Prowler and give the new Owner a $2,000.00 deduction so they can have the dash removed to repair the mode door.
I have a feeling that it could be a bad BCM but really do not know if that is the problem.

Again, THANK YOU to everyone that provided suggestions and ideas, they all helped in the process.

I have ordered a new HVAC Blower Control to replace what I have now per your suggestion. I will let you know how that works out. What I noticed after I did the work on the BCM is that the air would come out the dash after the reset and then after a short time it would go to the floor and then go to defrost. I tried to reset the mode door by disconnecting the battery ground for a little over 60 seconds and that is what the result was. I performed the reset several times again and the result was similar two what I had in the beginning of this project. Basically I did not see any change in the action of the blower mode door than what I had in the beginning. I will try anything that might work as I do not want to have the dash/instrument panel removed which is what the manual says has to be done to get at the mode door motor assembly. The mode door moves it just doesn't seem to stay in the correct position as it moves by itself without any change in the selector switch and always ends up in the defrost mode only.

I received the blower switch assembly (Blower, Air Direction, Heat/Cool and air source. I purchased mine from Rock Auto as the one they had seemed to be a very good quality unit and I have had some problems purchasing items on e-Bay in the past with quality and misrepresentations. They had two (2) versions and I purchased the better one. I have not had a chance to install it yet and I thought, depending on room, I would just hook up the wiring before I remove the entire unit from the Prowler to see if that is the problem. It looks like there are two (2) plugs and of course the two (2) cables to change.

Thanks for your interest, I will let you know what the result is. Probably will work on it next week as this has been a recover from a big wind storm week, lots of small trees and bushes down. Just found out that I have fourteen (14) dead trees on our farm that have to come down, good thing I bought the switch assembly before i found out about the trees. LOL

Regards,

AJAK

I have decided to put the Prowler away for the Winter and I plan to replace or test the Blower Switch Control in the Spring. The weather is going to get bad and I wanted to get the car ready and put it in storage. I also ordered a Mode Door/Motor Actuator in case that needs to be replaced. Thanks for all the suggestions and interest in my problem. I will post my results in the Spring. Have a great Fall and Winter.

Regards and Thanks,

Well, so much for the reset sequence working. I have not driven the Prowler since I posted about this issue beginning October, other than in and out of the workshop.

Tonight I was moving it back in and decided to play with the new stereo and noticed that the air coming from the vents kept changing. I turned down the music and kept hearing a click every few seconds, and the air would change. UGH. Crap. It it still doing it. This makes the car undriveable (to me at least), especially in the summer.

If I find anything else out I will let you know.

BTW, does anyone know the part number for the BCM ?

Discontinued Part

prowler store has and exchange program 700 core and repair 1300 to 1400 hundred.

It might be the door actuator
Actuator - Mopar (4815502AB)

you could try having it repaired

So Dano your problem sounds very similar to AJAK problem.
Both of you have attempted the reset procedure no luck
He did try the BCM removal and clean . no luck.
He did order a new Hvac switch but hasn't tried it yet due to winter storage.
His last option after the switch was to replace the actuator door.

BUT...for what it is worth, I was searching through the internet last night looking for a BCM and saw a BCM for a Caravan and this triggered my memory. Many years ago we were purchasing a Dodge Caravan from a used car dealer. He jumped the van to get it started so we could test drive it. The dash was going crazy and the bell would chime randomly. We came back and told him and he said 'oh yeah, that is because it needs a new battery'. I was like 'BS DUDE'. He was positive about it so we took the van and got a new battery for it. Dangit - he was spot on. It cured everything.

So...I noticed that the gauge in the Prowler keeps showing around 12.5 - 13 volts. I'm thinking hmmm...so I ordered a new battery today through a friend of mine that has a dealer account with Pep Boys and I will install the new battery. If for some reason the problem goes away I will never know if was cleaning/dielectric for the BCM or the new battery, but I will be one happy camper!

Replaced the battery, removed the BCM and cleaned the contacts and coated with dielectric grease.

It worked for about 5 minutes and started malfunctioning again, although this is nothing new as it has worked for short periods before.

Removed the electrical connectors from the back of the switch panel and reinstalled them (hoping for a loose connection)...same thing.

Then it quit moving the door altogether...it does NOTHING now.

One thing I noticed...when it worked correctly the rear window defogger also worked correctly. When it stopped working, so did the rear window defogger. It just might be coincidence...and it might not. Interesting though.

So...nothing new, nothing working. If and when I get it fixed I will let you know. Until then $H1T !!!!

I have discovered that the mode door actuator will move when I turn on the ignition. You can hear it moving and then stop. It then can be heard pulsing very lightly and that never stops. If you leave the key off for a few minutes, it will do this same sequence again.

I unplugged the switch panel completely and the rear defogger continues to randomly turn on/off (I can hear the relay clicking), and the door model actuator does the sequence I mentioned above.

I am wondering if the BCM is the culprit?

Does anyone have a BCM that they would like to sell ?

A few days later I called and left a message. No one called back.

Looking for a new replacement option, I found that Chrysler has a rebuild service for these for around $500, with a $750 core charge. Brandon at Dallas Dodge once again came through and turned me on to this service.
