Re: Heater quit... sort of
Add one more satisfied user of this thread! I did the repair on my wife's Highlander yesterday. It was blowing hot air regardless of any other settings. Opened things up and found two broken wires. Replaced all three and voilą, we have control of the temp again!
One note. I had seen references to not being able to completely remove the back cover of the control unit because of the ribbon cable connecting the back to the circuit board. I immediately recognized that the ribbon cable goes into a connector on the main circuit board that allows the ribbon to be EASILY removed. There is a collar around that connector that can be pulled up ever so slightly using your finger nail. Pull it up from each end, it only moves about a tenth of an inch or so. Don't force the collar any further, it is permanently retained to the connector body. Once it is up the ribbon cable slides right out, allowing you to get the back panel out of your way. When you are putting things back together, be sure you put the ribbon cable all the way back into the connector (so none of the silver finger portion is visible) then gently push the collar back down. Be sure it is down all the way around the connector.
