I had my yellow lamp failure sensor box go out, but had managed to keep it up and running for a couple of months with a soldering. However, it's failed again, and the replacement from the junk yard wasted no time in failing as well. I don't know anything about electronics, but having checked and replaced all the bulbs to make sure the proper ones are inserted and in good shape, I assume the lamp failure sensor is burning up due to a bad ground somewhere. I don't see any signs of distressed wiring, even around the trunk hinge.
Is there a tool I might buy and check things out myself with a little instruction, or is my next stop an auto electrician (who I fear will tell me I need to replace the wiring harness)?
By the way, my power antennae went bad (would crank down but not up). The mechanic manually got it into the up position. Then, to keep it from maneuvering down again when I shut off the radio, he disconnected the wiring to it by unpluging the connector at the top of the blue box (that sits just below the yellow lamp failure sensor box). Would disconnecting this have any affect on the current to the lamp failure box that might cause it to fail? I also notice there is a larger plug at the bottom of the blue box. Would it perhaps be better to unplug that one instead? I'm a blind squirrel reaching for straws here, to mix a metaphor.
One other note... I had the engine replaced not long before this problem started. Is there some common oversight the mechanic might have made in relation to the electronics when installing the new engine... one which ulitmately might have led to this problem? If so, perhaps its something I can check on.
Lastly, and totally unrelated... out of curiousity, what the hell is the large black plastic vent like part numbered 62940-32010 that sits below the lamp sensor box? Is this some kind of vent for exhaust fumes or what? I can't figure it's purpose.
Thanks!
