124 wiper motor and transmission compatibility?

Can anyone say for sure whether the wiper motor and transmission (linkage) assembly from an 87-93 car will fit the 94-5 124 cars?

Ebay has several units for sale, most appearing to be for older 124's. The EPC (Electronic Parts Catalog) indicates different part numbers, but I'd still like to know if you could fit the earlier unit to the later cars.

Thanks,
Chris W.

I've had them both out and they both mount exactly the same, and have the same electrical hookup, but I never actually swapped them out.

but the 94-95 one lets you use an off the shelf BOSCH wiper blade.

I have some of the new units. Email me ifyou want to buy one.

We are talking about the windsheild wiper assembly right?

Answering my own question...

I obtained a wiper motor/trans unit from a recycler - supposed to be a 94/5 unit, but when I got it home it appeared to be somewhat different from what was on my car. The gasket arrangement was different, and the housing for the wiper arm was different, and the drive motor itself was slightly different.

To make a long story short, it works fine. The biggest pita was taking the gasket off my old unit and putting it on the new unit. I'm talking about the gasket which covers the bottom of the windshied, then goes around the wiper blade base, and continues on across the windshield. This is all one big gasket. The junkyard unit appears to have had a two piece gasket, but it had been removed on the unit so I'm not sure.

I brought the old wiper unit inside to let everything warm up, and to clean the crud out of the channels in the gasket. The gasket is clamped to the wiper blade base with a stainless band clamp, which is basically not made to be reusable. Pry the end up and off and release the band. Now the gasket can be rotated, with some effort. To get it off, you just have to STRETCH it over the mounting arms of the transmission frame. It seems impossible that it will stretch that far, but it does. (don't try it if it's cold!) Use something to help lever it off. Likewise, when putting it on the new unit, it helps to have a lever to assist. I was able to use the band clamp again by bending it back in shape and carefully hooking the end in place.

Put it back in the car and did a test run before buttoning everything back up, and yeah! I've got a decent wiper again! There's always the risk that the junkyard unit is worse than what you already have!

The motor on the old unit had some sort of capacitor or trap or something bridged across the + and - leads, and the junkyard unit had no such gizmo, but everything seems to work normally. Maybe for radio interference or something? I dunno...

Rgds,
Chris W.

Hey, could you post pictures or email them to me?

the 94/95 unit will allow you to use standard off the shelf wipers unlike the early model which have aweird offset.
