1996 S-10 Blazer, When you put the rear hatch down washer fluid runs out of the jet put hatch up it stops.......HELP :1zhelp:

does the washer work normally or does it take a few seconds tostart to spray

look for a GM TSB I forget what the number is but we where putting a 1 way check valve in the rear line to stop that problem

sounds like it need a shot of penacillan :P

Check under the rear compartment sill plate. There is a small opening with a wiring harness and the check valve.
