1991 GMC Suburban V8 Two Wheel Drive Automatic

hey guys thanks for the great opportunity to post questions and get answers for our problems. I have a 1991 gmc suburban and I lost all my wiper delay functiopns, it only works in fast and slow. Anmd errastically at that.I read an answer to a similar question and it indicated that therer is an electronic board within the wiper motor itself but I looked under the hood and I cannot see any electronoc boards with that motor. The wires go thru a connector into the firewall. Does anyone have any idea where they may go? I eould apreciate a schematic even hand drawn! Thanks a million. John

The electronic board is mounted on the motor. It maybe on the back side where you need to pull themotor to replace it. It's pretty simple to do. It costs about $50 to fix it. If you do it yourself and aut parts stores may have it orable to get it instead of a dealer.
