the front wipers of my 84 hatch haven't worked for since before this last summer (they worked fine then) but its gettin to be time to fix it.

 

i'm not sure if the two systems share components but the rear wiper works fine, always has.

 

when the switch for the fronts is turned to INT, the "wiper intermittent relay" (metal cylinder about 1.5"x2") clicks about once a second and the wipers do nothing. in other positions nothing happens at all.

 

so i went to the bin in my garage with the brat's vehicle harness and pulled the wiper relay off, same part # and everything. put it in and nothing changed.

 

i never touched those wires in my spfi conversion or a/c delete except that i unplugged/replugged the wiper motor a couple times while fishing wires in that area. checked it and the connector/pins seem fine. fuse is good, car's never blown a fuse in my course of ownership.

 

 

any ideas?

nevermind...its the switch. i forgot that there's separate connectors for the fronts & rear so i didn't think i could try the brat's switch. once i remembered i plugged it into the hatch's front connector and the wipers worked fine for a minute.

 

i tied the brat's witch up under the dash as a temp fix then tried the wipers again to make sure and nothing. now the wipers don't work at all again and the relay just clicks on INT, nothing in other positions. it seems both switches are shot.:-\

 

guess i need to find another hatchback/wagon wiper switch.

 

if anyone's got one laying around, please let me know.

i disassembled & cleaned both switches. both look good, connectors have no corrosion but the wipers still don't work. the rear wiper/washer pump works w/ the hatch's and the front washer pump works w/ either switch. if you put the wiper switch to INT, there's no wiping and the relay still clicks about once a second. in LO & HI there's no wiping or clicking.

 

these same syptoms are present with any combination of the 2 switches & 2 relays.

 

Try adding another ground to the wiper motor body.
