Multifunction switch replacement

[RYC CUKR]

I am pretty sure that the multifunction switch on my 88 is the problem. I have no low beams only high beams, no intermittant wipers, no washer and no low speed wiper only high speed.

So I am going to change it out. Is this the correct part?

Dang suckers are expensive.

yes you have the correct part, and it does seem to be your problem. I have changed them out before, not to hard. Shop around, im pretty sure you can find it cheaper than that. I think I bought mine at autozone but im not real sure what I paid for it.

A word of caution about multifunction switches is in order here. The multifunction switch (high/low beam, wiper, turn signals) are different for different years. 87-98 will work in any 87-89 car. The 90-93 switches only work in 90-93 cars. You can't put an early model switch in a late model car, nor can you put a late model switch in an early car.

Autozone and advance both have the turnsignal switches for the 86 listed for 87-89. Looks like I am gonna have to shell out for one from 50resto or another restoration shop or try the bone yard.

I had one from a 93 in my 87 and it worked fine.. Go to a local pick and pull down on colonial and get one for like 6 bucks.

You can put a 90+ MFS into a 89- Mustang....but you need to repin the connector. I can't remember off the top of my head which pins need to be moved...but you need to move two wires in the connector in order for it to work. I put a 93 switch in my 88....which works well because the 93 switch is longer than the 88, due to the airbag steering wheel. So mine sticks out further than it should, making it easier to hit. Not that it was all that difficult in the first place.

Oh, and about the connector. When you change your MFS, be sure to check the pins in the connector. Those connectors tend to break very easily. The retainers inside the connectors break off allowing individual wires to come out of the connector. A lot of times it is the connector that actually fails and not the switch itself. So pay extra attention to the connector..make sure all the wires are in their correct place snugly.

Cool thanks for the heads up. I will check the connectors tomorrow to make see where the problem is.
