How do I take off the leaf guard between the window and the hood to try and get some lubricant down to the heater blower? I pulled the wipers off but the guard looks like it is riveted to the firewall?

Also, what the heck is the switch to the right of the light switch?
I have an original owners manual and it doesn't call it out, and I've searched and searched and found nothing. It turns and it has a little curved arrow graphic.

Some good news, my gauge lights are now coming on! Not right away when I turn on the lights but after a few minutes they come on, very nice! And I pulled off the boot at the base of the turn signal arm, re-soldered a black wire and now my wipers fold back down to close on their own when I turn them off. Before they would just stop where they were when I turned it off.

Bad news, my blinkers have stopped working. (This happened before I did the work above) I've checked fuses and bulbs, they are fine. Any ideas of where to track down the problem?


Thanks!!!

Not sure about the switch (post a pic?) could be your dash light dimmer, but here is your solution to the blinker problem. You just need to refill the blinker fluid reservoir...no need to use original MB fluid, either. Just pick up a bottle of this online:

Blinker Fluid Refill

oh, yes! The blinker fluid, how could I have missed that one??? And here I've been moving the seat back and forth thinking that was it.

I wonder how many jugs of that they have actually sold?

Check the "rivets" on the leaf guard. If they are original then they have a plastic center peg which pushes through releasing the "rivet". Use a small Phillps screwdriver, cotter pin, electric probe, etc., to push it through. Try to keep track of the centers so you can re-use them.

If someone has replaced them with pop rivets then you'll need to drill and replace them Use aluminum rivets, not steel to prevent rust streaks.

None of my W114's have had a switch to the right of the headlight switch unless you are talking of the one in the gauge cluster which is indeed the dimmer switch. It's pretty common for someone to have soldered a jumper wire across the dimmer rheostat rendering the twist function moot.

Are your emergency flashers working? Turn signals and flashers use the same relay to operate.

Don't listen to Palolo, he's over in Hawaii and Pacific Island blinker fluid won't hold up to the harsh conditions we get here in the Continental states. Plus that, I've been to Hawaii, don't nobody there pay any attention to turn signals!

Funny thing is for the longest time, until I got the owners manual, I thought it was the light dimmer. See pic.

I have the switch removed. It says Bosch Impulsgeber. Searched google for that and couldn't find anything in English. It translates to Pulse Encoder.

And thanks for the info on the rivets. The car has been painted and those are painted over, I'm guessing/hoping under the paint they are still the plastic ones.

Hawaii? I bet they sell gallons of blinker fluid over there, too much sun all the time!

PM Frank Reiner. I bet he'll know what the switch controls. My best guess would be some kind of dealer installed cruise control.

The car's too old to have warp speed capability so it wouldn't have "impulse drive" either.

I think I figured it out. Found a german thread about VW's and I think it is some kind of intermittent wiper control! Man would I love to get that working. Intermittent wiping is almost a necessity here in the PNW.

Has anyone heard of this option on these? I saw where on later models it was integrated into the wiper control stick.

And the emergency flashers have never worked. When the blinkers worked, I had to move the blinker arm up and down to get them to blink, but at least they would come on.

Where is the flasher located?

There are two possible types. One, the most likely due to the year, will be a pull knob on the center console and the other will be a rectangular push button. The pull type is usually the far right knob in the center console.

Triple check your fuses, don't just look and twist at them. Pull and clean them, inspect the seating ends and clean the spring receptors. Relays are sensitive to proper voltage and if they don't get clean current they can cause all kinds of intermittent operation.

The relays are located behind the switches. The type you probably have will require pulling the center console. The knob unscrews and you have a retaining nut holding the unit to the console. They are pricey little buggers but most of the time you can refurbish the unit. You can also bypass them with a standard 2 prong flasher unit as a last resort.

Is the mystery knob an Idle Adjustment?

Keep us informed on how the heater blower lube job goes, I need to do this as well. Are you dribbling ATF down a long pipe or something?

I don't think it's an idle adjustment. Weren't those only on diesels? I started another thread about the heater, with some pics. I'll post up there how it goes.
I haven't tried ATF fluid.

crojack, you inspired me to deal with my "dead" heater blower. Where I live in Northern AZ, we hit freezing last night and the car windows were frosted - so I thought I had better get the blower going or go to plan B (a replacement motor or blower "scheme")

With the info given by MikeD in this thread, I accessed the fan through the intake outside the car. I cut an access hole to the motor. My fan was very hard to turn, but not rusted out. I first used Brake Cleaner, then I used WD40 then I used a lightweight oil. I was skeptical but even the 3 speed switch got it running no problem!! I was really pleased. I put it all back together, covered my access hole with aluminum tape.

Now I need to deal with the fact that I have heat on one side of the car but not the other. I already went through the heater control valves, rebuilt it with new O-Rings. I guess I will need to try to flush out or Back Flush out the heater core, if that be the issue. The Air control from Defrost to Floor works, but the temp on the bad side just does not get very warm.

Always something on a 43 year old car - step by step!

Chris
