Hi all, this is my 1st time. Please can someone help. My wife has a W reg 2000 CLK 320 convertible. last month in sub zero temperatures her park sensors started playing up. This sorted itself out when it warmed up. Now the lamp (bulb) warning indicator lit up. Had a look and the number plate lights were not working. Also noticed the rear foglamp warning light (the little orange one) was lit up a little. The rear fog also was not working. I went to have a look las weekend, opened the boot and suddenly the ignition lights came on. Shut the boot and they went out. Everytime I open the boot the ignition lights come on. You can't even put the key in to release the lock. When I disconnected the fog lamp connector in the boot the warning light went out and the switch operation was good again, bar the lamp not working. On testing there was slight voltage to the fog lamp?? Has anyone experienced these symptoms. I am totally lost on this one. Please can some of you top guys help.
