I have a 2 relay trim motor with white plastic reservoir on bottom in a 1988 Cobalt with Mercury v8 motor,
The trim switch at the throttle will not raise the trim, no hum or click at motor, the switch does raise the trim though. I also have separate dashboard mounted trailering switch and that does raise the trim. I did some experimenting and i jumped both relays at the pump and that enabled the up and down cycle individually.
BTW-Can someone explain the difference to me between the up trim switch and the trailering switch, is it just to save my butt in situations like this?
Lastly while i was there, i removed all the old fluid with turkey baster and refilled with fresh tranny fluid. I overfilled the reservoir and fluid immediately started to seep out of the upper seam on tank. Is that a vent there to atmosphere or do i have a crack along the seam. I reduced the volume of fluid and it stopped.
Thanks
