Blower isn't working

I changed blower motor regulator today(S320 -95) but after replacement blower isn't working anymore and the climate control unit isn't showing tempature on display, and on the central ventilation both lights are on, red and blue. Fuses are okay.

Is the problem in the climate control unit perhaps? Blower and climate control unit was working before the regulator change, but now those arent working...not with the new regulator or with the old regulator.

regulators from ebay fo 20 eur are known to cause similar problems. they usually work form several hours to several weeks. Mine started both leds in the dashboard at center vents like you described. so there is a big chance that this is a case if you have put in an aftermarket regulator.

If not, then check wires and connections which you moved.

the next idea is to remove minus terminal on a battery and wait some time. maybe AC control module needs some rest and all will be fine with new regulator if the current one is not that one for 200 - 400 eur (i do not know the exact price but they are expensive).

All I wish for Christmas is a smooth idle.

Could also be the blower motor. Do not buy the cheap regulator. The best one comes with a thermal pad instead of the thermal paste. The pad is a more exact thermal conductor. They will be about $150+/-. If you use the paste be sure and use enough.
