Re: Washer Pump

I believe the Trico 11-515 isn't a new gear drive unit. It's an electric pump setup to mount in -place of the gearbox and mechanical pump.

Re: Washer Pump

How would that Trico pump mount? I don't see how the stock pump could be removed, since it is integral with the wiper motor assembly - not detachable like the 73-80 pumps.

Re: Washer Pump

Also, when you push the pump button on the windshield wiper switch, does it send an intermittent signal to the pump mounted on the stock wiper motor, or is it continuous power of a set duration? If I use the wires to the stock pump and attach them to the universal motor, do I have to keep the button depressed to get a squirt of water, or does one press of the button give me a predetermined duration of power to the pump?
