: i've got a 97 transam and today when i lock the doors and set the alarm
: instead of the 2 horn chirps and the fog lights blinking the headlights
: pivot open then close and the motor on the left light spins for about 10
: seconds. anybody ever encounter this. thanx, rick
Stripped gear in the headlight motor. Very common.
The sound happens because there is no limit switch to tell the computer that
the headlight is closed. What happens is the headlight hits a stop which
then stalls the motor. The current through the motor shoots up and the
computer senses it and shuts it off. Since the gear is stripped, the motor
never stalls and the computer doesn't shut it off until it times out after
a few seconds.
I see that in another response there is a pointer to Brent Frankers homepage.
There is some good information there. The "fix" is to disconnect the headlight
from the motor and rotate the motor shaft 180 degrees to utilize the
"other" side of the gear since the motion to open and close the headlight
only uses half the nylon gear. This is a temporary fix at best because you
will wear out and strip the other half of the gear over time as well.
At that point you will have two choices: 1. Spring for a new headlight motor
or a used one from a junkyard. These are also temporary fixes since the
replacements will also have the nylon gear that is the real weak link in
the design. 2. Buy a set of replacement gears and permanently fix the
motors you already have. Brent offered at one time (and still does, I presume)
a replacement gear made from brass. I purchased a pair of these for my
TA and have not had a problem since. If you are going to hang on to the car
for any length of time, I'd reccommend the purchase of the brass gears. They
are easy to install and permanently fix the problem.
