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.
