My wagon wouldn't shift and I had to use the shiftlock override button to shift. I checked the brakelight switch and it was ok. The fuse was not shot either. After taking the shifter cover off I found the problem to be that the little triangle shaped plate to the right of the shifter which contains the copper contacts that slide was corroded a bit and not making good enough contact to unlock the shifter. I took it out, removed the metal plate and removed the little plastic arm inside. I then bent the contacts on the plastic arm out and sanded the copper tips as well as the copper slide plates. I then greased it with fresh grease and re-assembled. It did not work at all after I reassembled and I was pretty hacked off. It didn't work because during re-assembly I popped the 8 amp fuse to it. A new fuse and it works like a charm. Hope this helps!

I haven't had a chance to check mine (also a '93), but do you remember if there was enough room to actually remove the solenoid (to try to repair it) altogether?

Fortunately the solenoid was not functioning properly due to lack of electrical contact. When the brake was applied it would pop open but a second later would close back again. During this test a small puff of smoke came from the copper connector. After cleaning and readjusting it , works fine. Not sure if there is room. Sorry I don't have more definitive answer for you. Good luck!

coca cola or diet sprite in there?

knowing mrs.zorak, probably coke...lol...
