Highlander 2005 So, I decided to replace the stock radio tonight, and I popped out the climate control section (which I didn't disconnect, but just left dangling).
When I restarted the car after reinstalling everything, I observed that the first two controls' backlights (fan speed and heat gauge) were not working, but the third (air flow direction) was.
They functioned before I removed the climate part to replace the radio. Could one or two of the cables have been severed? Could it be the bulbs?
How do you open it to see whether the bulbs are blown?
