Speedometer stopped. Odometer still goes.

My sister has a 1991 Volvo 740 GL 4 cylinder 4 speed automatic rear wheel
drive cant remember if it has ABS or not. Her spedometer has stopped
working but the odemeter still keeps mileage and the cruise control still
works and maintains speed but its anyones guess how fast shes going. She
was in an accident and the passenger side rear wheel was struck and
knocked out of round and warped the brake drum, rim, and wheel hub so all
that was replaced. She thinks its a wire or sensor in the rear and I
cannot find it if thats it. But it doesnt make sense to me to think its a
sensor when the mileage is still going. I have resoldered all the
connections in the dash so what else could it be? I know Volvo is bad for
electric problems but all are easy fix. This is just a mystery to me. Any
and all help is appreciated. Thanks! =)

 

If your speedometer doesn't work and your odometer still does, the
problem has to be in the speedo head, they both use the same signal.
The speed signal for the ABS is shared with the speedo, and is located
in the differential cover.
