wiper motor gearbox grease

took my wiper motor apart to find all the grease in the gearbox had hardened. i've cleaned it all out but i'm wondering if there is any particular grease i should repack it with.

i have some white teflon bike grease at hand...

I believe you're supposed to use a special dielectric grease so that the parking contacts will still work if the grease gets under them. An electrical shop should be able to provide it.

i don't follow... dielectric grease is an insulator...

Do believe that dielectric grease is a conductor and anti-corrision grease that I use on every electrical connection that I can reach. Good stuff for errant grounds, etc. Keep 'em rolling, Vlad

but the word dielectric means insulator. i think dielectric grease is just a good water seal.

I may have used the wrong word there. As I understand there's a special conducting grease that should be used so that the parking switch can't lose it's contact on the gear.

but if the grease conducted then it would be conducting even when the parking switch was against the insulated piece and the wipers would never shut off...

Dielectric grease is not conductive however it protects electrical connections and wiring from salt, dirt and corrision. Also known as silicone paste, it can be used as a rubber lubricant and conditions rubber products without potentially harmful solvents (spark plug boots etc). It is also used in electronics to aid in heat transfer. (White stuff between transistors/microprocessors and heat sinks.) When you slide the connectors together there is metal-to-metal contact and the grease gets displaced but the area around connector is protected from moisture.

Hope this helps.

ahah, i thought i could keep under the radar jeff, but i can see you've matched my list of problems to my true identity!

anyway, you're right - the white stuff works fine. better than gearbox oil, i'm sure :)
