just noticed it this morning. I can wiggle the shifter while in reverse and get them to flash or come on for a second. I did a search and got 60 or so hits, but they were for wiring extra lights. Is there a prox switch or something on the trans that picks up the shifter position?.......Has anyone had/got this issue? Did you correct it? If so, what did you do?

I have not had a chance to look. TIA for any help.
If I get it corrected today, I will post the fix....if it is not raining :....Shortround

Yes, there is a reverse switch the screws into the side of the transmission. It is pretty easy to find. Make sure that it is attached to the transmission housing securely. That may be your problem right there.

 

RamDan03 - thanks for the info. I will investigate this afternoon.

BACKUP LAMP SWITCH
DESCRIPTION

Vehicles equipped with a manual transmission
have a normally open, spring-loaded plunger type
back-up lamp switch (Fig. 1). The backup lamp
switch is located in a threaded hole on the side of the
manual transmission housing. The backup lamp
switch has a threaded body and a hex formation near
the plunger end of the switch, and an integral connector
at the opposite end of the switch. When
installed, only the connector and the hex formation
are visible on the outside of the transmission housing.


OPERATION
The backup lamp switch controls the flow of battery
voltage to the backup lamp bulbs through an
output on the back-up lamp feed circuit. The switch
plunger is mechanically actuated by the gearshift
mechanism within the transmission, which will
depress the switch plunger and close the switch contacts
whenever the reverse gear has been selected.
The switch receives battery voltage through a fuse in
the Integrated Power Module (IPM) on a fused ignition
switch output (run) circuit whenever the ignition
switch is in the On position. A take out of the engine
wire harness connects the backup lamp switch to the
vehicle electrical system. The backup lamp switch
and circuits can be tested using conventional diagnostic
tools and methods.
