I have a T660 and the wipers intermittently stopped for a brief second the other day and this morning woke up to no wipers. Switched relays and checked fuse. Both good. I pulled the harness connection and only have power to the red wire with the wiper switch in the full speed position. Switched through the various speeds and still only have power to just the red wire. I'm assuming the wiper motor is bad but maybe someone with a little more experience knows of something electrical I may have missed?

Sure it's not the wiper arm bushing stripped had to replace mine last year

Where would I see movement if that were the case? I dont see anything moving on the linkage

It's been a while but they were cheap at 4 states like 50 I think for my t660
