The rear air con/heater doesn't work.

sorry, didn't manage the pics but you know how it looks like.

Are you able to place a finger on each relay, whilst turning on the Fan switch and increasing it up to Max. ? If so you should feel the G3-20 relay click when first turned on and the G3-18 relay click when Max fan speed is selected, likewise when turning the relays off you should be able to feel the clicks. If there is no click then it would suggest that the problem is back into the controls, if they do click but no fan then that would suggest that the Fan is seized up (unusual for the rear). Other than that it will need a meter to try and sort out where the power is getting to and what isn't working.

hello... again.
The relay click when on max speed and off.
can it be anything with the Fan or it will be the motor?

thanks

Have you checked the two 30 Amp fuses under the bonnet (either side of the green fuse) ?
If the relays are BOTH clicking and the fuses are OK, then that points at the electric motor that turns the fan, but its a bit of a pain I think getting into the box, so I would check with a meter if you can that power is getting to the both sides of the relay contacts;
You should see +12volts on the G3-20 relay on the Yellow/Black at all times, and Black/Red when the relay operates.
You should have 0 volts on the Blue/Red of G3-18 when the fan is on Max, and a voltage around 2-10 volts at any other speed setting.
If you get the correct voltages above but the fan isn't spinning then there must be a fault with the motor/fan its either jammed or seized.
