wipers only work on high

hi um my wipers only work on their highest speed, i originally thought it was the switch, had that replaced, and then i thought it was the motor, but before i get a new motor is it possible that there is a relay or something else that would cause the intermitant speeds to not work? thanks

I beleive that there is a circuit board that controls the wiper speed. If the motor works in hight speed, then the wiper motor is good.

where is the circuit board and is there a way to test it?

does anyone know where the wiper circuit board is located? or is it possible that this is caused by a bad relay?

The wiper circuit board is located in the wiper motor assembly. On the backside of the cover where you see the electrical connector. Not to the motor itself. Underneath once cover/circuit board assembly is removed you will see the gears and park switch. I don't see any relays in that circuit that could cause your issue.
