I am attempting to repair the sunroof in my 2006 lexus RX400h. I recall when I purchased it heavily used, that the sunroof worked on the test drive. However, we couldn't pick up the vehicle for a few weeks due to traveling, and when we picked it up, it was bad weather for the season (Pacific Northwest). After spring came around, I tried to use the switch to open the sunroof, and nothing. No attempt at movement at all. So I tried to use the tilt switch, with the same results.
I purchased an extended warranty which supposedly covers the sunroof, but when I called, they said it only covers the sunroof motor itself, and not any diagnostics or any other parts of the sunroof assembly.
I am a very mechanically inclined person, so I figured, why not diagnose this myself. If its the motor, I can have the dealer fix it under the warranty I purchased. If not, I can fix it myself.
Today I decided to test the voltage at the switches (after checking all the associated fuses listed in the manual). The switch appears to be working, but only receiving trace voltage. When open, (not toggled) the switch reports zero volts (as it should). When toggled to either open or closed, the associated side of the switch reads 0.46 volts. This seems odd to me, but it is plenty to indicate to an electronic control module to trigger a relay to open or close the sunroof. Does anyone know what the voltage should be here?
Also, does anyone know the exact location of the motor assembly itself? I figured it would be right forward of the sunroof, under the switches & dome light assembly, but there is no motor there. There does appear to be a location for a motor to go into, but there is no apparent mounting locations for associated bolts. What gives? Did the shady dealership I purchased this from swipe my sunroof motor?!
Any help and information would be greatly appreciated!
