TECHNICAL INFORMATION TIP

Reference Number(s): TOY0283AP, Date of Issue: March 1998

DEFOGGER & BLOWER MOTOR CONTINUE TO RUN WHILE KEY IS OFF

YEAR(S): 1990

MANUFACTURER: Toyota

MODEL(S): Landcruiser

DATE OF ISSUE: March 1998

ISSUE & TIP

I recently repaired a 1990 Toyota Landcruiser with the following problem: If the ignition key was turned OFF while the rear window defogger was ON, the defogger and blower motor would continue to run, discharging the battery.

The cause: A loss of ground to the rear hatch (the upper portion with the window in it. Voltage feeds back through the rear wiper circuit, through the wiper and gauge fuses, and keeps the ignition relay activated.

The solution: Add a ground wire between the upper corner of the hatch and this chassis.
