For some time, I've been having a problem with my slide lock operating intermittently in both directions. It has progressively gotten worse and on our last trip, it stopped working altogether. After checking out the various threads on this forum, I performed the travel lock field repair. When I activated the lock switch, it promptly locked as designed. Thought I would check the unlock - NADA. After further research I proceeded to plan B, bought a tube of Loctite Blue and prepared to use that method after removing all the washers. Since I needed to get the slide unlocked, I hooked the motor to my portable drill battery using test leads and Voila, it worked just fine in both directions. No binding or hesitation. Hooked it back up and tried the switch. Nothing again.
So I have concluded that my problem is likely in the switch itself. Does anyone know how to get to that switch in the dash? It appears to be in a box of sorts and is totally enclosed with the other switches on the left side of the steering column. I'm baffled.
