hi y'all i got a strange one for everyones experiences, my wipers on my 99 350 only work like they're supposed after i leave the switch on for 20 min or more, then just fine but sometimes stick on and will not change speeds, the washer switch always activates them when ever i need them but thats getting to be a hassle, truck has new gem and malfunction switch, was going to try swapping the motor next but wanted to see if anyone has had this problem or a similar one.

cheer,

hmmm....multifunction switch concerns are usually related to turn signal/hazard light and/or pushed out pins at connector. but wiper circuit is rare....motor would be a suspect
