I have a 1999 Dodge Ram Van 1500, and when I opened the dash to replace a terminal AC selector switch, I noticed there was a blue electrical connector way behind the dashboard AC control panel that wasn't connected to anything:


What is this for, and what is it supposed to be plugged into? Any input would be appreciated.

Thanks!

 

Looks like connector C326 - Power Door Lock module.

 

AHA! Thanks! I bet that's why my power back door locks don't work. Now I just have to figure out how to plug it back in.

 

I opened the doghouse today, and found where it goes:

So apparently this van had remote entry at one time, and it was probably unplugged when the original keys were lost. It is probably possible to get a new fob and get it working again, but right now that is low on my list of things to fix.

 

Yep, get new fobs, but, I think the dealer has to pair them with the van.
