I have owned my 87' tc for about 4 years and recently my firm and auto ride switch has stopped working, i have tried pulling the switch out and cleaning the contacts but that didnt work. But i think that the real kicker is that when i step on my brake pedal i hear the electro-hydroboost kick in and then i hear my firm ride kick in and then the light turns on, any one have any solutions?

Switch is open in AUTO mode and closed in FIRM mode. Might want to short the switch terminals and see it it goes FIRM all the time. In AUTO mode, does it go to FIRM when is is supposed to (hard braking, going around a corner any faster than your grandmother would, speeds over 84, large throttle opening)?
You can run the PRC diagnostic test with the test connector under the ash tray. There are instructions somewhere around here I think.

The switch comes on when there is hard braking, and high speeds, but when i turn the switch over to firm mode it will not come on, ii have tried to clean the contacts on the switch but i cannot disconnect them.

The switch is bad... Mine use to do that although I was sometimes able to get it on firm by repeatedly trying the switch. Replaced the switch with a used one and it works fine.
