The only wiper set up I'm really familiar with is the 2-speed wiper which uses a unique motor from the 1-speed set up. My coupe has a 2-speed wiper and I'd really like to add a 2-speed wiper set up to the wagon which came with a 1-speed wiper set up. I know I need a 2-speed wiper motor, 2-speed switch and the appropriate wiring, but do I also need a different wiper arm transmission assembly? I'm talking about the arms that are under the cowl grill and are driven by the wiper motor.

TIA.

Rich the 1 & 2 speed square motors use the same linkage and the 2 speed round motor uses one different arm. It is the long arm from the motor arm to the passenger side.

Rich,

I show that there are 2 different part numbers for the wiper transmissions, 1 Speed PN#4913871 and the 2 Speed PN#4914507. I don't know what the difference between the two is though. Perhaps it's length or the bend where it connects to the motors arm?~? :eek:

There is a two speed square motor that uses the same arm and transmission as the one speed.

I'm looking to install the 2-speed round motor so I guess I'll need to find the appropriate transmission arms too.

If you can't find the parts you can always use an aftermarket delayed wiper control from JC Whitney.

Rich you have mail.
