Thanks for you videos and comments. I have a 2008 Nissan Frontier and all of a sudden my doors will not lock or unlock with my key fobs. I have new batteries in them and they have been programmed correctly. Just all of a sudden they will no longer lock or unlock with the fob. Do you think the BCM is the problem? Where do you think my BCM is located and how can I troubleshoot it? Thanks for the imputs

[@drcoolautofix]

Definitely, however scan & validate for u01000

A warm salute from the caribbean.Very well explained. Could an inoperative tachometer and speed odometer,coudl be a posibility of a bad Bcm?

[@drcoolautofix]

Yes in some car make, cos they are routed through the bcm or rear sam

I have a 2013 Ssangyong Stavic - Car has automatic locking at 50kmph. However the car will continue trying to lock the doors after they have already locked. And will then unlock as the car slows down. So car is constantly locking/unlocking the doors while driving. The aircon also works intermittently. Sometimes will be really cold, and other times feels like the heater is on with the same aircon setting. - I also have an electric window on the drivers side which is very slow to go back up. Could these all be symptoms of a faulty BCM?

[@drcoolautofix]

It's likely

Hi there, I have a 2019 Chevy Equinox which has all sorts of intermittent electrical issues such as some or all power windows won't work for days and sometimes all or some work, sometimes the driver side door won't lock/unlock and sometimes it does, sometimes the interior lights works and sometimes it doesn't, sometimes the display changes from audio to android phone and vice versa and sometimes everything seems just fine and so on and so forth. This has been happening on and off since almost a year now after I bought this brand new. All fuses and relays seems good. Neither the Chevy service center nor auto electrical technicians can figure out the problem. Already spent some $$$ and these issues still remain, though the car drives great otherwise. Could this be the BCM issue or something else? Please advise. Thank you.

[@drcoolautofix]

Likely

[@earthlycreature8772]

@@drcoolautofix Thanks for your reply. What else would you suggest to check before I venture into BCM?

[@earthlycreature8772]

I was recently told to remove the BCM and clean it thoroughly with an electronic cleaner including all terminals, plugs and check for any loose connections and damaged wires that are attached to the BCM.

[@gilr5737]

Does the driver info run thru the BCM? The input switches do not work but the display will show the different thing that are possible. I just can not select thru the menu item and get the displays.

[@drcoolautofix]

What's the car make and model?

[@gilr5737]

Saturn aura 2009

Hello, I have a Ford Focus mk2 2005 If I put the gear in reverse Or roll the windows up or down Or switch on the front or rear fog lights, they don't work. Instead, the water pump works. Do you think it is possible to be a bad BCM?

[@drcoolautofix]

Check blown fuses

[@MRizk-wr4oo]

@Dr Cool Auto Fix I checked all fuses and wires, nothing wrong
