joshua102888 Posted February 8, 2008 Share Posted February 8, 2008 Hi, i have a 92 es300. My passenger side turn signal never worked, so i took off the headlights yesterday, and noticed that the Printed Circuit was burnt, and black. So i took it off, and figured that it was the reason for the bulb not flashing. I cleaned the housing, and bought new bulbs but still no luck. Here are exact pics of my printed circuit.

dcfish Posted February 10, 2008 Share Posted February 10, 2008 Have you contacted a lexus dealer ? If so what did they say ? Get a part# and do an internet search. I wouldn't replace them with a used part. Quote Link to comment Share on other sites More sharing options...
CUMan Posted February 10, 2008 Share Posted February 10, 2008 How can you be sure the part is bad by just looking at it? I would think you could check whether voltage is getting to this part and then being routed to the connection points by using a multi-meter.

Those circuits are one sided, And you can clean them with care, I agree, Either check them yourself or have them checked for continuity.

Lexucan Posted February 10, 2008 Share Posted February 10, 2008 Looks to me like the three or four tabs at each end need cleaning. Those are the contact points. If you don't get continuity with the volt-meter, try gently scraping the taps with an x-acto knife to remove the oxidization. Quote Link to comment Share on other sites More sharing options...
