When I started my car in preparation for the journey down to Silverstone for the WSR on the Friday evening, I put the headlights on to find just one pop-up headlight working. I first of all did the obvious fix of loosening the manual adjuster which I am told is the normal problem with the mechanism. This did not work. As I didn’t have time to look into the problem, I drove down to Silverstone with the non-working light put up manually. I noticed when I got to the hotel that when I turned the lights off the mechanism retracted the headlight as normal. I did at this point try the headlights again but found it still wasn’t raising the headlamp.
Anyway, last week I had some time to look into the problem. After taking the cover off the back of the headlights, I first checked the mechanism but couldn’t see anything obvious.
Next thing to check was the control module as this is often the problem with pop-up headlights. Fortunately, the part is exactly the same part as used on the Lotus Esprit (which I just happen to have parked next to the 610 at the moment) so tried the 610’s module in the Esprit. It worked fine. I also managed to get hold of another module which also worked fine in the Esprit but didn’t work in the 610. So that was ruled out as the problem. Incidentally, if anybody does need a reconditioned control module then I can get them done considerably cheaper than a new one would cost.
The relays and fuses were checked but weren’t the problem. Next up was the motor. This is also shared with the Esprit so had access to a new one to test. Didn’t think it was the motor though and it wasn’t. So all that ruled out.
I then had another problem develop. The front left indicator stopped working whilst driving the car. Coincidence? Checked the bulb and wiring and everything was fine but the unit wasn’t getting enough power to light the bulb. Looking at the wiring diagrams, it became obvious that there was another set of connections somewhere. Eventually found it by the brake reservoir/fuel tank.
Undid the clip, disconnected the plug and found this
Used some decent contact cleaner and both problems sorted. Hope if anybody else has the problem, it may help save some time in identifying the problem. Cheers
