2002 Suburban rear wiper module

[Throbbin Rods]

Hello all, new guy here. 2002 Suburban. 1976 Jeep CJ5 I am restoring, 7 boats being rehabbed to sell, one Labrador Retriever.

I have been chasing a problem with the rear wipers in my 2002 Suburban. Over the last year I have replaced the motor and the switch. The thing continuously tries to park and then jump, providing me with a nice beat going down the road but a serious case of the AARRGGHH's. I am beginning to think it is the pulse module in the rear. I was unable to find any motors anywhere in my area that came with the pulse module. I had to put my old pulse module on the new motor I bought. Anyone here know of the part number for the rear pulse module or a place where I can buy it? Thanks in advance, seems like some real knowledgeable folks here, looking forward to spending some time catching up.

Thanks

Bill
