Well, as I posted before I purchased that 84 928S and I have been going through it with a fine tooth comb. Lately I have been working on the washer system. My car is equiped with headlight intensive washers in addition to the normal system. I have the following problems:

Intensive washer system not working... bah I found the switch had fallen apart under the dash, intermittent wiper switch broken too, gonna replace em both.

Headlight washers operated from the stalk... they WORK! They sprayed a foamy brown crud all over my car lol.

Windshield washers... hrmmm nothing from the stalk at all, no electrical noise or anything. I can clearly hear the headlight pump.

I searched the boards for info on this and saw how rust in a couple of fittings is common. I pulled out my bottle and am in the process of removing the rusted part and flushing it. Guess I am going to have to get the neck out too and take the metal sleeve out of it as well.

I think I have a bad windshield pump and I see that on my car it is located in the engine compartment, I guess its next to the bottle on S4 cars. Looks like the thing is barely screwed down though, there are locations on it for putting fasteners in but no evidence of them. My washer bottle has an orange plug in it where the S4 motor plugs in.

Anyways, my question is: is the washer pump supposed to be mounted in the engine compartment and if so, whats the easiest way to get it out. I have already checked the fuses and they look fine, could it be a relay?

Why doesn't the idiot light for washer fluid come on? When I took the tank out it was nearly bone dry.

Thanks again,

I believe our cars are the same so...

The headlight pump is on the bottom of the main fluid tank.

The intensive washer pump is at the front underneath that tank.

The windshield pump is inside the engine bay on the right fenderwell, roughly below the coolant tank.

The windshiel pump is muonted by four rubber plugs. These get brittle over time. I rigged a new pump with bolts through the stock holes.

BTW - some report being able to disassemble the pumps and clean them. The gears of the pump can get jammed. I haven't made that work, but at ~$30 a piece, might be worth a few minutes to try.

 

The windshield pump looks like its nice and cozy under several steel lines (A/C?) as well as the coolant reservoir and washer fill nozzle. Exactly how much stuff do I have to dissasemble to get it out, I am pretty sure its the culprit. BTW my level sensor is now working, must have got stuck in the open position by a ring of scum, or maybe the PO pulled the plug on it to sell the car, who knows.

I found it easier to get mine out by putting the car on ramps and attacking it from underneath. It was easy; a quick yank on each of the rubber standoffs will snap them off. They are only a few cents each, so get 3-4 new ones with your new pump. If you use new standoffs, spit on them a bit so they slide easy and pull them into place with some needlenose pliers. If you try to bolt it in place you'll be fiddling with it for a lot longer, plus the vibration will transmit through the body when it runs.

 

Not if it's shimmed with some rubber peices. A few cents? Those are $3 apiece at 928 Intl. Hey, saved myself $12!

Update: the pump is $46!

 

I'll have to check my receipts. but IIRC the pump was in the mid-to low 30's and the standoffs were relatively cheap.

 

The PO pulled my pump and relocated it and wire tied it right up by the water tank filler on top of a few hoses. It is one of the few times I appreciated the PO! It seems to work fine there and is very accessible. As to pump dissassembly, there are a few screws that hold down the front metal plate. Once you pull those off you can clean the crud out of the pump gears quite easily. All of mine worked fine once they were cleaned out.
