Re: climate control replacement

The rear window defrost has nothing to do with the climate control,
Stephane. It is an electrically heated grid powered from the switch in the
dash. Check the fuse & the switch. If these are OK, check the wiring
connectors to the window grid and check the main grid lines (vertical lines
at the sides of the window) for breaks.
