Have some wiper trouble on my 93 f-350. They only work some times as low on the fist setting, or some times only on HI and wont quit untill the truck is shut off. Even in the off poshion. Read a few treads about the Wiper contrile module behind the glove box malfuntioning.....
Took a peek on mine, looks like a black 5" x 7" box with a plug on one end...
Could this be the culpret? and if so I have acsess to a parts truck, (98' PSD f-350) would this be the same?

It would be the smaller of the two the large one is the RABS. Could be the wiper motor too, or in part the MFS on the steeling column.

Hi, i have a 89 F250, i found my contoll module for the wipers right beside the headlight switch. I opened the module and found several cracks on the soldiering of the circuitboard. My wipers lakced normal speed, interval function and self parking. I see that you have a 93, so i'm not sure that you have this module at the same location.

ah, mine lacks the self park feature also, i'll take a look.
Any one have a part # for the Wiper controle module?
