Power Locks & Windows Went Out

I have a 2003 Aztek that I've driven since 2018. A few months ago, I was driving and had to hit the break pretty hard to avoid a crash. Immediately after this, my "service vehicle soon" light came on and the power locks, windows, and cruise control all stopped working. I thought a fuse had blown but all of my fuses are fine, and the cruise control LOOKS like it should be working fine, just isn't. I haven't had any other unusual or major issues since this has happened, but can't seem to figure out what is causing this. Any info or suggestions are greatly appreciated!

It may be helpful to scan the vehicle and check for CAN bus communication between the serial modules. It could be that the PCM can't signal the body control, door modules, ABS/traction, and other systems.

2003.... When did can start? Class 2?

Thanks! If this is the issue- what would the fix?

I know the '03 Saturn and some Buick/Cadillac had CAN, and by 2006 everything used it. Not sure of the Aztec/Rendezvous platform.

Your have to get a full system scan report back all stored trouble codes.

What size engine? All windows don't work at door switches or master switch? Plus all locks and cruise control? Check engine light on?

I will look at wiring schematic. If mil is on get code scan and report back all module codes.

3.4 engine? Need to know if you can operate door locks and power windows from master control switch and from each door switch. Report back results.
