Hi all, I have a 1997 NAS 90. Until yesterday my parking brake light was working fine, then it came on during a drive and has stayed on. I searched the forum and found its also connected to the Brake Fluid level, I checked and this is full, I also cleaned the connectors on the top of the sensor, light is still on. Checked the parking brake switch and nothing appears to be broken. The wiring diagram doesn't really help.Switches are damned expensive imo so I'd rather not solve with buying parts unless its necessary.
Any other ideas?
Update, dodgy wiring at the switch

check to see if the switch on the hand brake is working. It is a switched earth.

Both switches switch to ground. If you disconnect the wire to each switch, the light will turn off when you disconnect the switch that is causing it to turn on.

Loose connections would prevent it turning on. A stuck switch or a wire shorting to ground, would cause it to stay on.
