Has anyone experienced this before. My power windows all switches, sunroof, and power mirrors all quit working yesterday. I have checked the fuses and they seem to be ok. Anyone with any ideas as to what the issue could be? Thanks in advance.

 

Battery

 

Quit working from the driver's switch? Switch reset.
Quit working completely from all switches? Fuses.

 

I tried the switch reset in that I held down the down and then the up position for several seconds but no change. I have checked the fuses inside the car and they appear to be fine. There are separate fuses for the left and right windows along with a separate fuse for the sunroof. I did notice a 50a fuse in the box under the hood that indicated it was for the windows but it looks more like a relay and I am not sure how to tell if it is bad. The battery was replaced with an OEM from Acura about a year ago and while I will not totally discount it as being the issue I doubt it.

 

One thing that I did not mention is the underlying reason this happened is KARMA, I had just picked up my new 2015 RLX 5 days before this happened. My 2005 RL has been a solid dependable car with 10 years and 147,000 miles of service without any major issues except for the A/C compressor going out last summer. I guess she was mad about being replaced, although she will still be remaining in the family since my son is becoming the new owner. Proof that cars DO have feelings I guess!

 

Did you do the switch reset at each door or at the driver's door? You have to do it at each door.

Do the sunroof and mirrors respond at all? If not, it may be worth trying an electrical reset by disconnecting the battery terminals and holding the cables together for 30 seconds. Of course, make sure you have radio and Nav codes first.

 

No response at all...tried the battery reset, that was ineffective also. Thanks for your suggestions.

 

You can't visually inspect fuses, use a multimeter and test for continuity. Something being dead is a fuse or relay.

 

Going out on a limb and saying something chewed up a harness.

 

Take the car in and have the battery checked. Living in Texas heat, I chewed through a battery every year. Here in the South, the heat is brutal on the electrics.

 

Dropped it off at the dealer last night. Will know by this afternoon the diagnosis . Hopefully it won't be too painful.

 

Dealer has told me that the master switch on the drivers door is causing the issue. Part has been ordered and I will know tomorrow if that fixes the problem.

 

Been there, done that!
