wiper crapping out
I have a very weird problem: For 5-10 minutes my wipers work just fine. Then they start "stuttering". The motor stops for a second, then goes back on. It wipes once or twice, then is off again. Then it stops twice per wipe and gets worse and worse until the wiper only moves inches before stopping again.
I already changed the wiper motor. What else could that be? Has somebody had that problem before? The wiper runs for ages if I switch it off between wipes.
I don't get it!

I had the same problem. I changed the wiper motor but it did not fix the problem. A buddy of mine who is a mech. told me about a little black box about 2X2 square (can't remember what its called)that is behind the dash board wired into the back of the switch.
I changed that and all was well. It was a long time ago but I bought it from the dealer for around 80 bucks.
I think it went bad from the bammm shock when releasing the parking brake. So now I release the break with my foot on it gently.
I also think I have read posts about people fixing the circuit board inside the black box, by soldering bad connections.

Thanks for the replies, guys! Sounds like the interval regulator. I'll look on the junkyards and if it fixes it, I'll be very gentle on the parking brake! 
I'll post the reults here!
Thanks!

I found the Wiper Control Module. Easy to take out and check. There was a big resistor on it that was completely loose. I soldered it back on, but haven't tried it, yet. If that didn't fix it, I'll post again. If you don't hear from me again, it worked.

Well, the big thing seems to have been a capacitor, since the intermittent wipers now work again (they never have).
However, it didn't fix the wiper from stopping to wipe after 5 minutes continuous wiping. I now got one off Ebay and will see if that fixes it...

I already changed the motor and that didn't fix it. The new wiper control module came with a switch, so then I'll have everything switched out 
I'll post as soon as I got it all working...
