Commander Electrical issues

I just bought a commander and didnt realize it had so many issues. I am hoping someone has had these issues and can help me.. I am stumped.

First and foremost, the door locks only work with the remote or will work with the door switch when the key is turned off. If I turn the key on, the door switch no longer works but sounds like it will attempt to unlock only but doesnt lock at all.

Second problem is the passenger window from the drivers side switch acts like it has a short in it and will only go down or up a little bit and stop.

Third issue is the interior lights. They will turn on whenever the illuminate switch is turned OFF, but after I turn the switch on at any level, the lights no longer work. Also, if I turn one interior light on and turn on a second on, they both go dim. If I turn on a third one, they all go out completely.

Fourth issue is every single time I turn my illuminate switch at all, the service 4wd flashes.

Fifth issue is my traction control never turns off whenever I engage 4wd low or any time. My jeep goes into 4 low as normal but the traction control light never comes on.

Sixth issue is my odometer section is burnt out and my fuel gauge doesnt work.

Seventh issue is smaller but still could be related... my passenger door speaker is muffled and the dash tweeter doesnt work at all.

Eighth issue is my heat is really hot when driving and even when I try to turn the temperature to cold, it still blows hot. The fan switches all work but still blows hot air when Turner to off and the temperature is all the way cold.

I can point you in the right direction for the last issue. XKs have a gear that links the heat/ac blend door to the actuator motor that tends to break. Depending on whether you have single zone or dual zone climate controls, and which side is having problems, you should check on either the left or right side of the dash.


If you have single zone, or are having troubles with the drivers side heat, pull on the panel directly underneath the steering column and it'll flip down for you to access the actuator motor. The motor will be mounted on the air distribution box towards the center of the vehicle, and is held on by a few Torx screws. The passenger side is mounted identically but opposite, and you'll need to remove the glove box to access it.


Once you see the actuator motor, take out the screws and pull out the motor, then check that the gear is still intact. If it isn't, unfortunately Chrysler doesn't sell it separately, but you can try to search eBay for a 3D printed part or make one yourself.

Thanks for your help! I have single climate control. Is is the gear that is bad or the part that holds the gear? What is the part called that I would search for?


Is this the reason my heat wont cool down no matter what the temp control is set to?

Yikes!!!

There are so many weird issues here that are incredibly rare. This rig must have been under water at some point in its life.

You may be looking at a ground issue. I didn't spend too much time scouring wiring diagrams to see what circuits fit your concerns and where they ground, but by proximity G303 under the drivers seat would be one I would want to check out. I would also want to look at G200 (sorry no picture available) that is listed as "By the data link connector". I would unbolt each ground, clean the body and the eyelet on the wire, and bolt everything back up.

Two "no-cost" items you can do:
1. It seems that many of these issues may run through the multi-function stalk (LHS of steering column). Recommend you remove it (only 3 trim screws and 3 mounting screws), clean the contacts with plastic-safe electrical cleaner, and then re-install.
2. Under the dash, on the LHS are the interior fuses and the large junction block. [You can access it easier if you drop the knee block trim first.] There are 2 large wiring connectors (C1 & C2 ?) that sometimes come loose or may have a poor electrical connection. Power for door switches and interior lights runs through here also. Recommend you check these also.

The fuel gauge and odometer are part of the instrument cluster sub-assembly and so are normally serviced as a unit if it is an inside problem. Replacement needs to be programmed with VIN and mileage IIRC. Don't know if the MOPAR StarScan is required to do this.

Basically, there are three pieces; the blend door, the actuator motor, and the connector between the two. I think it's properly called a lever, but there isn't a part number for it. It typically breaks, so the actuator motor still turns but the blend door won't, meaning it's stuck on full heat all the time.

This is a 3D printed version of the part I'm talking about. The seller has also included some pictures of where the part goes.

Look up the DIY threads at the beginning of this forum. Chirpz has a good how-to with photos. Part no. for recirc. door gear is given. Search that on e-bay and you will come across that one and the other one for temp distribution. Think they run ~$21 each IIRC. Newer design is more robust. Just did my recirc door using the foregoing.

That's a different gear. The issue here isn't with the recirc blend door, but rather distribution box linkage.

There are a few different linkages in the AC system that tend to break; there's one tucked above the glove box, by the blower motor, that more commonly breaks. It controls the recirculation door, and it's readily available on eBay and other sites. Depending on whether your recirculation works, that may be the cause.

Your heating problem is related to the other linkage, the one I linked to in an earlier post. It's tucked below and to the right of the steering column, and controls your heat/AC blend door. It's a much rarer part to break, which unfortunately is why they're difficult to find and not often mentioned.

I know that.
The OP wanted a part number for the part on the LHS. What I was trying to advise Commanderwv07 is that the part number for the blend door (RHS under glove compt.) is provided in chirpz's DIY procedure. When I did a search for the recirc sector gear on e-bay, I accidently discovered the other part (LHS by steering column that the OP needs) also listed. At first glance, they are almost identical and I started to order the incorrect piece, as I really needed the recirc sector gear. This answers his question regarding part number since the dealers do not provide it.
FWIW, the new ones look as though they have been beefed up in the web area, where the gear breaks.
