Reply With Quoteno one has any ideas?
is it possible that the contacts are dirty inside the light socket, and that's why I can only get the turn signal to light? Or is a dreaded LKM problem?

Turn signal works, parking light doesn't
On the front left of my car. Wires all seem to be attached to the harness properly. I changed in a new bulb, same result. Any ideas?

Could be the LKM, although the LKM doesn't switch any current on that circuit, only monitors it. Power comes in on pin 28 and goes to the light on pin 11 of the black connector. I would also check the connector and socket for the bulb, inspect the wires just before they enter the socket, the insulation commonly cracks there and moisture turns the wire to green dust.
Wouldn't/shouldn't the LKM report the problem with the park lamp through the CCM (since it is monitoring the filament afterall). Hrmmmm.....

The LKM reports the problem, "Parking Light" but the turn signal filament continues to function. I will check the wire connections more closely.

Don't forget that sucker is sectional. you have the socket AND a plug to check. Time to break out the multimeter

My money is on a corroded socket or a terminal not making contact wiyh the base of the bulb. LKM does not "see" the filament resistance so look for the cause of an open circuit.

So I took the harness out again today to test with a multimeter and one of the wires fell off - so that would have been the source of the bad connection now, don't you think?I soldered it back on and all is well again.

Just for my education, can you plse confirm this is the same bulb? And if so is it located within the headlight unit? I've driven in the US quite a few times and could never get used to your red indicators and brake lights coming on at the same time! And dont get me started on 'you can turn right on a red light'...

Park and turn signal are same bulb with two filaments.

it's the front indicator, which has 2 filaments. And don't worry, I live in Montreal, which does not allow right turn on red - one of only 2 places in north america that doesn't!
