LOOKING FOR SUGGESTIONS OR ADVISE: 2013 Ram 1500 5.7 liter quad cab

We had a heavy rain a few days ago. on the next day, I went out and started my truck and realized there were some issues. Truck starts and run fine. here are some of the issues: air conditioning does not work, radio does not work, front power windows do not work, (but rear ones do work), power locks do not work. Outside temp reads -40 on dash. I am not sure what else may be wrong. I have checks the fuses in the fuse relay box. Some have no power feeding them at all, others are just fine. Any suggestions as ro what direction to go next would be greatly appreciated.

Disconnect the positive battery cable, wait 10 minutes and reconnect. Might 'reset' everything.

Always remove the negative cable first,never disconnect the positive cable first or by itself,and always reconnect the positive cable first then the negative cable.Not going into the reasons why,you can google them,lol

Amazing the truck still runs.

no joy on the reboot. Thanks for the advise on the battery disconnect, but was already aware. I am looking for a wiring schematic to try to look for uniformity on the circuits that are being affected. Thinking it may be an issue with Body control module. Doing more research. If anyone has run into this issue, pls let me know.

This one has me puzzled. I have not seen an issue like this before.

Curious - does it have a sunroof? Odd question I know but recently my kids car had the sunroof drains plug up and it rained and the interior of kickpanels leaked water all over the BCM and pedal position switch causing all kinds of electrical issues. Long story short - cleared it out, got it draining as it should, dried out the components and all is well again. Pretty sure the BCM on these trucks is in a similar location. It's a stretch but I figured Id throw it out there just in case...

No sunroof, but we got 5.5 in of rain in one hour. I will take a look to see if there is any moisture on or near.

I suspect a partial failure of your BCM. It might have to be scanned by an FCA tech to verify.

How old is the battery ?

 

[KC Cryptkeeper]

I would check the door modules for moisture or a ground that got wet or corroded. the windows, locks and temp. all are controlled from the drivers side door module that is my reasoning.

 

[mrOAP]

Moisture in the fuse box, TIPM? Don't know how the rain would work its way in there, but water has a funny characteristic of f$%#ing up someone's day.

 

[rlubbers]

well had to take to local dealership. Diagnosed a shorted door module on drivers door. Part is on order will have truck back on Monday. Thanks for your suggestions. Good Call KC Cryptkeeper

So you've got a part repaired but I would be on them to make sure they resolve where and how the water intruded into the door module in the 1st place. The amount of rain would have little to do with this, more so the intensity and I'd suspect you'll get a similar rain again sooner or later.

You've made a good point.There is a YouTube video about TIPM being vulnerable to water

The TIPM on my truck is right behind a pretty large gap between the radiator and the washer tank. I was going to cover it up but I'm wondering if that's there to cool the TIPM?

Anyways during a good rain that gap is going to spray water on it at highway speeds.....
