Problems with the position lights in the Renault Megane II

In this post we discuss a typical failure in the lighting system of the Renault Megane II model (all engines).

                                    

SYMPTOM

A failure in the position lights on the right side prevents them working properly. There is a high probability that the respective fuse has blown and that after replacing it the problem persists.

If the error codes are read, no stored failure will be detected concerning this problem.

MAINTENANCE SERVICE

1-  Check fuse -F7A-, of 7.5 A of the Switching and Protection Unit, which manages the following elements:

 

Right rear position lamps

Right front position lamps

Lighting of the speed control knob (if equipped with it).

Lighting of the ESP system control knob (if equipped with it).

Lighting of the sunroof control switch (if equipped with it).

Lighting of the heating button on driver and passenger seat (if equipped with it).

Lighting of gear display (automatic transmission).

   

2- Disconnect the right front and right rear pilot and operate the position light switch
. If fuse -F7A- does not blow, the problem will be in one of the two lamps, otherwise continue with the intervention plan.

3- Disconnect fuse -F7A- and check all its wiring. This wiring is designed for those models with heated seats, whether they are equipped with them or not; in any case, the wiring is installed in all vehicles of this model.

4- In many cases, the short circuit is caused by one of the two connectors that activated the heated seats. These connectors are located within the central console next to the handbrake lever. The movement of the handbrake lever can cause cuts in the cables, causing a short circuit. 

Elements:

1) Left seat heating switch

2) Right seat heating switch

3) Hardtop switch.

4) Window control switch.

5) Handbrake switch.

REMEDY

Repair the wiring and isolate both connectors to avoid contact with the handbrake lever.
