See my Cave, Dash Dimmer
Guessing wheel is bad or still have problem on the dash cluster.
OE radio? Does dimmer dims the radio? If so... likely not the dimmer.
Use volt meter to check dimmer wheel works.Warning: Don't short the transistor.
Pull transistor socket a bit and measure volts between grn/wht and ground.
Volts will move when wheel is turned.
other trans pins
D 12-14v when HL switch in on
C Volts will move more when wheel is turned.
But C can lie when the cluster etc has problems.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
