Alright guys my 2000 ram 2500 has no interior dome lights, no chime, no heated seats or fob locks. I did some research and found a possible BCM was bad. Replaced that and nothing wtf. Is there a fuse or something I can check cause I’m at a stand still with this? Thanks

 

IOD fuse. (ignition off draw....)

 

fuse is still good though

 

by BCM do you mean CTM?

 

yes sorry I think I’ve heard people call it different things

 

Did you get one with matching part numbers?

The IOD would not cause the heated function to fail, only the power movement, the heated seats are given power by the CTM (possibly a separate module) only when the engine is running to prevent battery drain.

 

yes it’s the high line edition module I got and it made no difference

 

I understand the IOD fuse is good but have you replaced it? If the radio, and power mirrors work, i suspect the IOD circuit is just fine though

My memory is a little gray, but the CTM is mounted above the accelerator pedal in the dash? Was there another module beside it?

 

yes I have replaced the IOD fuse, radio works and powered mirrors work. Yes the CTM is mounted by the accelerator and no not that I could see I only saw the ctm.

 

I was thinking there was a security module of some sort, do you have the security system or just the keyless remote entry, Red LED under the trip computer would indicate factory security

EDIT: scratch that thought after minimal research the security is part of the highline CTM
