Thread: All windows stopped working simultaneously

Hello all!

So earlier this week all my windows stopped working at the same time (2004 Grand Prix).
No response from any switches.
No noise when switches are pressed.

Checked the power window fuse (really hard to get to by the way), and it's fine.

Is there a relay in either of the fuse boxes that could have failed to stop all window function?
Or is the relay located in the master switch?

I've taken out the master switch, currently trying to figure out if that's the problem.
Could replacing this be the solution to my problem?

Any other suggestions on what could make all my windows stop working at the same time would be awesome.

Thanks!

Either the 25A circuit breaker failed or the D/S window switch...check to see if you have power at the yellow wire on the D/S window switch...also, does the P/S window work from the P/S window switch? If it does, then it's not the circuit breaker...it's the switch. If not, then you're looking at a circuit breaker, RAP relay, or BCM issue.

Hey Sven thanks for the reply!

The P/S windows don't work from their respective P/S window switches either. (I thought if the master switch was faulty, none of the other switches would work either? Please correct me if I'm wrong.)

The 25A circuit breaker you mention is the component located at the back of the inner fuse box?
If so I've already checked that and it's good.

I haven't checked whether power is going to the D/S window switch or the RAP relay; those will be my next steps

Thanks for your help! I'll let you know who things go!
