I'd start with wiring diagrams.

Here's a diagram of your fuse block in the passenger floor board. You'll most likely have to remove the entire panel to gain access to the circuit breaker.

Spot 30 has a 20a circuit breaker. You'll want to check and see if it has tripped. If it has, replace it and they should work.

Then report back.

Sometimes a simple fuse can be the answer.

Hey lowrange2.
This is a great fuse block diagram. What years does it cover?
Good post no matter what.

Did this issue ever get worked out?

Tell you what, I'll fill in where the original poster left off...

Same problem. Wipers worked yesterday, now they don't! Although I believe by coincidence my rear wiper has stopped also. Thought maybe it was just gunk and/or rust because over the last few days when it's on it would stutter at the apex on the starting and returning cycle.

May need help diagnosing that, but first I'll check the fuses on the front and report back.

that sounds like a bad ignition switch to me... but im not 100% its a 2000

some development. haven't had time to mess with it due to illness but the last two days driving to work, wipers do not work in the morning but do work in afternoon. 12 min drive to work... it's been between 20 & 30 degrees here. made sure any snow or ice was cleared off blades and made sure they'd be capable of free movement before running so as not to stress motor. is the cold wx screwing with the motor or motor just going bad? Day 3 tomorrow...

The Rooster

Does your radio work? defrosters?

jakodemus

happened again this morning. everything works except the front wipers what seems to be in the morning. even after my engine got up to full temp... nothing. I'll go check it on my first break in about a hour. at this point can I rule out fuses?

jakodemus

So 630 this morning they wouldn't work. But now 830 and they're fine. I should point out at 630 there was no resemblance of movement at all. just completely dead. seems like its time to start addressing the motor?

The Rooster

was it really cold dismorning... maybe they were frozen?

jakodemus

It's been between 20 and 30 F overnight the last few days. Whenever there is any hint of snow I make sure to lift the wiper arms and jostle them around a bit to make sure they aren't frozen to the windshield. I've made that mistake once before... Will check the fuse today...

The Rooster

no i mean where the motor and where it plugs in... there could be a lot of stuff in the cowl where the motor sits... maybe even water... Sorry I was not more clear on that...

jakodemus

So, I've semi decided to replace the wiper motor. I took the cowling off and was actually surprised at how clean it was in and around the motor. No sign of water or any debris.

Checked an O'Reilly's and Autozone, they're both around $60 for a motor. Checked a junkyard and they've got one for $35 but they confused me by asking me if it was left hand side or right hand side. ??? There's only one motor. Right?
