Hey everyone! New here, but need some help.
I have a 1994 full size Blazer. 200k on it, just picked it up and I'm rehabbing it back into shape to be a nice daily driver. Having trouble getting the front windshield washers to operate.
I assumed the pump was bad and just replaced both for GP, even though the rear did work. Rear works fine, nothing on the front. No power to the pump. When I turn the switch on the turn signal stalk the wipers run, but no washers.
Did some searches and read about the pulse board issues, and according the wiring diagram the washer is fed from there, so I replaced that. Same thing, hit the switch, wipers run, no power to the washer pump.
Wiring seems good, everything else electrical works correctly on the truck. Wipers work correctly in all settings. Fuses are all good. The only thing I can think of is the switch on the stalk, but according the wiring diagram that talks to the wiper module which sends to the washer pump. So if the wipers run when I hit the washer switch that should mean the switch is good, correct? Is there a relay or something I don't see?
Anybody have any guidance to offer? This truck is newer than what I usually work on (other project is a 1970 C-10), so I'm a little stumped here.
Thanks in advance!!!!!
