I checked the wiper motor, the relay and the intermittent switch but some times worksand some time not works.
Loose wiper fuse.
connections.
it's and old car, and anything is possible this old. and is.
there are 2 paths I walk and more.
1: visual inspections of each related part, connectors etc.
2: then lay in traps. i use a thing called a VOLTMETER.
i connect it to the motor, (some times for a week)
and when it fails, I look at it. oops i got power to the motor
so the motor is dead. NOW.
or no power, so the supply is bad.
so in that case>? i move the meter test point backwards,
to find WHO dies.
its that simple, and a meter cost $20
even a rusty ground to the wiper base motor mount.
good power means both 12v and ground .

what you want to do is take a test light find the electrical plug thats hooked to wiper motor, either unhook it and test the plug with switch and key on or poke in the wires and see if it lights test light, if no light then i would say its switch, if it lights than its wiper motor. I don't know of any relay for wipers.
SOURCE: blower motor does not work
I had the same problem, replace, replace, replace. Check, check and recheck. What I found was the blower motor resistor, located in the blower squirrel cage area, two prongs and a curly wire, was bad. Took the new one back, (it ohmed out okay, continuity ok, all ok!) replaced it with another, and Bingo, problem solved. Frustrating to say the least. After two relays and a blower switch, and test, test and retest. It was a faulty resistor. Made in Mexico. And no guarentee, even though new, it works. Trial and error. Even the dealer parts are Honcho en Mexico. Thanks NAFTA. You gonna make us all welfare babies.
SOURCE: i was just curious if there is a relay switch for
there is a wiper relay in big fuse box under hood but might be the bcm ( body control modual)
