    Driver's side rear light melted into light socket. Picked up a replacement at AutoZone for $ 34. Now passenger turn signal light has gone out. The top of each head light cover is discolored, it looks like a heat related effect on the top of each sealed plastic cover.

    Front and rear left turn signal is out completely with the the headlights off and only rear will work with the headlights on. Blinker on dash comes on and blinks fast. I've spent about 8 hours trying to fix this issue and No luck. As I was in the front headlight assembly I seen that someone was in there before and jumped a wire to another on the same harness for that light. Not sure what that is all about but disconnect and the drl goes out. Very frustrated with this

    Front passenger Running light went out. Bought the replacement bulb (#5201) and followed video how to access and remove head light unit;so far so good. But when I went to remove old bulb & replace new bulb was another story! Seems impossible to get it to clip/plug in without doing damage! Is there a special way or tool needed to get it to clip in? Still trying to figure this one out! I noticed it was every weak a couple of days before it failed.

    Had to replace mine. I went to a auto parts store and bought mine, and had them replaced for about $ 400-$ 500 for both. At the dealer one headlight bulb is $ 500 each. To replace them the front bumper has to come off no other way to get to the front headlights.
