Hi everyone, I'm experiencing a couple of issues with my 2007 Acura MDX, and I was hoping someone here might be able to help.

I'm sorry if this is a question that has been asked before, but I haven't found anything that solves my problems yet. If there has been a similar post beforehand, a link would be very much appreciated!

I usually have my headlight switch set to Auto. When driving during the day, nothing unusual is happening, but when I drive at night the lighting of the interior buttons (backlit buttons on doors, head unit, steering wheel, sunroof control, etc.) flickers at random (~once per second). Same thing happens when I manually turn on the headlights with the switch. If the switch is in the Off position, the interior lighting and DRLs works fine, but my headlights and taillights "blink" every once in a while.

I feel like it could be the actual switch itself, the BCM, or maybe the battery, but I'm not a mechanic.

If any more information is needed, I'm happy to provide as much as I can. If anyone has had similar problems or knows how to fix these issues, I’d appreciate your advice! Thanks in advance for your help!

 

I’d start with making sure your battery terminals are clean. In addition to cleaning the terminals on the battery, check where the negative cable attaches o the chassis.

 

Just cleaned the battery terminals, but nothing has changed. I also disconnected the battery while the car was running and nothing changed either. I'll have a look at the cable tomorrow morning.

 

Disconnecting the battery while the car was running is probably not a good idea with all the electronics on these cars.

 

Apologies for the late reply, but that probably was a bad idea. I did check the where the negative cable attaches. There doesn't seem to be any signs of damage or anything I should be worried about, it just looks normal.
