Re: Hatch Motor Replacement

Does anyone have advice on where to start first while trouble shooting this thing. I don't want to waste time looking at something if I don't need to. The two areas I'm thinking are the switch and the breaker panel. Any advice would be great.

I had a similar problem and my mechanic said it was due to corrosion in the wires. What he did was wire the main hatch switch to trigger a pair of relays that would directly connect the lift motors directly to the battery with 10 guage wire for minimum voltage drop. Its a complicated solution but it works extremely well. The end result is the motors are directly connected to the battery instead of through the old thinner corroded wires. (hehe)
As for replacement acculift motors, If your motors are old enough you will have to buy new ones. I know this first hand as i had to replace mine. One was bad but I replaced them both and the work very well (and quieter too)
