I suspect the A/C amplifier in my 1999 Sienna LE is shot. The compressor clutch doesn't doesn't engage, even though the LED on the AC control button lights up.
The compressor clutch winding measures 3.4 ohms, but isn't getting +12V. Does anyone out there know where the A/C amplifier is located in the vehicle? Anyone know of a source for refurbished or new A/C amplifier?
p.s. it just went over 200K...going for 300!
