My GW had been "triked" when I purchased it and all worked well for about 6 months. After that, I began having problems when attempting to use the reverse function. At first it was intermitten and has now become an all the time problem.
The malfunction is that when reverse function is activated and the starter button is depressed, the mc will only backup about 4 or 5 feet (3-4 sec) then stop with the reverse indicatior going off (neutral ind not on either). To continue in reverse, the reverse button must be released allowing the unit to switch back into neutral, then repeat the action all over. This can be done again and again. Unit was put into the dealers shop for 2 days, to no avail, with the reverse/cruise module having been changed. (No charge for that since the problem wasn;t fixed) I've since discovered that if I simply release the start button and after a count of 3, then depress it again, the dis-engage/engage action does not have to be done. I can simply dis-engage/engage the start button over and over. Kind of herky-jerky but eventually gets me where I need to go. Does anyone have any ideas?
