Title: wiper question
Post by: Low82C10 on October 01, 2012, 08:24:45 pm
what is the difference in wipers? as far as delay or intermitting....the reason i ask is, i have what i think is a two speed switch and its also a push button for the wiper fluid pump. i have the unit on the fire wall that im guessing is a all in one, wiper motor and pump. PO told me it has a 85/86 front end so im not sure if this is were the problem is, i also have a wiper fluid bottle with the motor mounted on it but the wires went to the bulk head and did nothing. my problem is....when i push the button in to squirt water, it just clicks. the pump wires in engine bay (pink,white)??? when i disconnect them only one has 12v when i push the button when the connector is connected they both have 12v and when i push the button one wire goes dead?

The washer pump receives power whenever the ignition is on.  The washer switch completes the pump circuit to ground.  Sounds like you have a bad pump.

Sure.  Pink wire is positive, white wire is negative.  Supply power and ground to those two terminals, respectively.
