I have read and followed all previous threads. Here is the problem

My 99 Saab 9-5 SE was recently acquired. I experienced the untimely death of my 2000 9-5 when my son was in an accident. I built a Frankenstein car out of my 2000 and a 1999 intermittent wipers won't make complete cycle. they creep along the windshield. Low and high don't park.
I replaced the motor with a motor from my other Saab which worked properly. No change. Replaced relay in fuse box in engine compartment. Relay clicks when intermittent wipers are activated. Is there a second wiper relay in the drivers side well by the fuse box. The posts are so vague. I'm going crazy. Dice also came from other Saab and I think the seat heat is also inop. No codes on tech two tool
