Please help/ Old woman car won't start
 

(Clever title should have read 'old woman's...'
Mother has a 98 V70 T5. Recently having series of mysterious electrical events.
Drivers side door power window is inoperative (seems to be jammed,) and car will not start. Plenty of power to turn over, but apparently no spark.
She's been having problems with alarm/ door locks/ windows, etc.

All the "usual suspects" have been eliminated, i.e. battery, fuel filter, etc. Car only putting out transmission/ ABS related codes.

What say you? Where should I begin?

Thanks in advance.

What are the codes?

Thanks for the quick reply. I've misplaced the readout that I paid Volvo 100 clams for. I'll post em as soon as I can. I believe one indicated a fault with the transmission range sensor, one indicated faulty MAF, one indicated faulty ABS module (and ABS pump motor,) and finally, both the rear wheel speed sensors are supposedly faulty.

Standby for the actual codes, if you don't mind. =)

Thanks again.
