RENAULT MEGANE HEALEFACCION HEATING PROBLEM

Good afternoon, my problems is that for some day the air conditioning/heating fan does not work, checking the circuit I see that I have no mass in the electronic module that controls the speed or in the relay that feeds on the circuit (side of the battery). Making a cable bridge and giving mass to the circuit this works.
Banding the electrical scheme, these cables go to a connection marked as "AV" and a dough intake marked as "mj" "electrical mass right front foot", but I am not a capad to locate them in the car. Could anyone tell me where these connections are found?

Generally this sta above the left foot of the driver, or on the transbersal bridge of the torpedo, depending on the year, luck ..

Thanks for the answer and we will see if there is luck with the location.

Hello Santiago, the mass connection that you are looking for under the plastic of the right front stop, you have to lift it carefully since it has some clips and in the lower angle of the DER door under the board is an 8 mm screw that adjusts the masses.
