Hey guys, long time member, 1st time post. I have an issue that I want to bring up and HOPE that someone has a fix for. I have a 2016 Lariat Supercrew.

Yesterday, my truck started doing some weird things while driving. My blind spot monitor and lane assist have error messages and stopped working. AC doesn’t work (no power), can’t roll down driver/passenger window from driver controls, but the rear windows can be rolled down by driver. Passenger can also roll down the window from their control.

Volume controls aren’t working from panel, but I can control the volume through the steering wheel. Dealership can’t get me in until sometime next week. Anyone seen anything like this?

 

What mods do you have that would involve electrical components?

 

Disconnect battery for 15 minutes minimum and reconnect.

Could be a BCM reset necessary (body control module) which controls a lot of item you have errors with. BCM shouldn't affect the radio and AC. However, any errors, and/or a check engine light will disable A/C. Assuming you actually mean air conditioning and not a fan which are two completely separate things.

Disconnecting battery for 15 minutes should reset the body control module. Report back in 30 minutes

 

How old is your battery? It is surprising how many weird things happen when system voltage drops below a certain level. This often occurs during start-up and prevents many of the electronic modules from booting up properly. I would first get your battery load tested. Then I would check under the hood for any loose ground cables. There are several. The main one is just left of the battery, but there are one or more that are on the cowl (not far from the PCM). If these are all tight and the battery is good, then I would check for DTCs with an advanced diagnostic tool such as IDS or FORScan. Many of the codes that can be broadcast are Ford specific and the cheap generic code readers will not see them.

 

Fog lights would be all. Swapped them out for LED’s about 2 years ago.

 

Thanks. I will give this a try and report back.

 

I replaced my battery about 2 months ago. Thanks for the feedback. I’ll try disconnecting the battery for the recommended 15 minutes or so. I’m not very handy when it comes to under the hood stuff.

 

Check for critters eating wires.

 

No luck with disconnecting the battery. Left it unplugged for about an hour. There could be a host of other things, but I am not mechanically savvy at all. I'll end up taking it in to the dealer, was just hoping for an easy fix, which is certainly still could be.

 

I'll try this. I did minor scan earlier, but will try a more thorough search for anything like this.
