Windshield Wiper Combination Switch
If someone can answer this and it works I will send them a check in the mail. My intermitant wipers do not work. Sometimes when I put on the turn signal or just make a sharp turn or sometimes run over a bump they will all of the sudden come on. I have already replaced the switch. That was a waste of $200. Does anyone have any idea? Oh yeah, it's on a '94 C280.

SEND ME THE CHECK!!!
It's the Wiper/Combo relay.
It controls:
The intermittent wiper.
Rear defrost.
Turn Signals, &
Hazard Lights.
Less than $50 on FastLane; $144 @ dealer! The relay is under a panel (6 screws) just behind the main fuse panel in the engine compartment.
"The problem is the Combination Relay, which is located under the black panel (6 screws) just to the rear of the main fuse panel in the engine bay.
This relay controls the intermittent wipers, turn signals, and rear defrost.
Prior to replacement of this relay on my 95 C280, I had the following symptoms:
1. Turn signal flash is irregular, or not operating at all.
2. Intermittent wipers worked totally randomly.
3. Flashing LED in rear defrost rocker switch when rear defrost was engaged.
The part number is: 201 821 02 47.
Good luck! The part is about $50, and is cheapest in FastLane."

David C Klasse....Where can I mail your check??? You are an absolute genious!!! I was just about to get on here to find out why my rear defroster doesn't work either and you just solved both problems! Sometimes when I put on my turn signal, my Lamp Failure light comes on. I'm sure this will fix it. Thank you very much! I LOVE THIS FORUM!!!

It Works!!!
If I had known it was something as simple as a relay I would have fixed it a long time ago. Electronics is something I'm good at. I just took the relay out, took the plastic sleeve off of it and re-soldered all the connection points. I put it back in and everything works. Thank you very much for the information.

David,
Pretty much the same as everybody else on the list.. just over all upshift is rough.. not a smooth transition from one gear to the next regardless of accelaration condtion(hard, regular,etc) ...sometimes it does feel like I kick in the back.
I've also noticed that if I am braking slowly, right before I come to a complete stop the RPMs will dip below 500 and/or bounce up past 1000. I would think this is the MAS but I've had it checked out. I think the problems are all related somehow. None of the dummy lights are showing a problem. No Check Engine, etc. So I'm at a loss.
The fluid level checks out okay on the A/T.

super3day,
Yes, it's true. I'm back in Florida. Working on a software job for a State Agency. Maybe I'll back in Colorado by the end of July. I setup shop in Florida(again) back at the end of September.

I have had the same problem with my wipers and just recently noticed problems with the turn signals as well as the defrost switch. After reading this thread, I took David's advice and ordered the relay from FastLane. I installed it this morning but noticed that the part number on the old part that I replaced is slightly different (201 821 00 47) as opposed to the part sent to me by FastLane bearing the part number (201 821 02 47). Furthermore, it seems the part I received has one additional prong/plug on the relay than the one I replaced. Is this normal? Did I get the wrong part?
There is one other thing. Just about a week ago (before I replaced the relay), I noticed that my left turn signal indicator on the dashboard goes into hyperdrive mode when turned on (i.e. blinks really fast) vs. the right turn signal indicator, which blinks normally. I assumed replacing the relay would fix this problem but it hasn't. What is the cause of this abnormality and can it be fixed?
Any help would be greatly appreciated!
Thanks,

First of all, I think you have the wrong part. This could be why your turn signal is on crack. I wouldn't just throw away your old relay. All it should take is some soldering. There aren't any moving parts or anything like that. Try putting the old relay in and tapping on it to see if it works. Let us know what happens. ~Doug

Hopefully I'll remember that someday when I need it! Otherwise I'll just needlessly spend $150.
