System Operation
A seat heater kit contains two (2) heater pads: one (1) for the cushion and one (1)
for the back To realize two heating levels (not available on all models), the two
pads are connected serially for the “LOW” position and in parallel for the “HIGH”
position. This conguration gives a lower rate for the “LOW” position and 100%
for the “HIGH” position. To avoid overheating, each pad has its own thermostat,
which interrupts the electrical circuit at a temperature of 158°F (70°C).
Seat Heater Use
The seat heater is designed to control the temperature of the lower and upper
seat segment of the front seats. Proper temperature control of the vehicle seat
increase the driver‘s and front passenger comfort. The seat heater operates in two
power levels and can only be activated with the ignition turned on. The switch
label “HI” is best used to power up the seat heater in cold ambient temperatures.
After the system is operational for a while the seat heater should be switched to
the “LO” position for maximum comfort. This keeps the system from generating
too much heat when running continuously. The low position will provide the
best comfort for normal operating conditions. The seat heater may be turned
“OFF” by placing the rocker switch in the center position.
The seat heater is equipped with safety device which senses and prohibits
overheat conditions. If the seat heater is operated for extended period of
time in the “HI” position, it may be possible for the thermo probe to shut the
heater down. In such event it may take a few minutes until the system reactivates without intervention from the driver (provided the switch is still in
the on position). A 10 Amp fuse protects against electrical shorts and other
malfunctions.

Troubleshooting:
If system does not heat up or no indication of power.
Check fuse in seat heater harness and vehicle.
Temperature of seat may be above the preset thermostat temperature and will not
allow it to come on. (ie: sun shining on seat)
If the light on the heated seat switch does not come on, it could be that the switch
bulb is burnt out (replace switch) or that there is no power to the switch.
Ensure that all connectors are properly connected and that the ground wire is
properly grounded. Refer to Figure 9 for wiring diagram.
Using a digital ohm meter, test only the heating elements (switch not included)
from the under seat wire connector. If no resistance is found, then an open
condition exists.
Check internal wire connectors for an open circuit. If a heating element has an
open, install a new heating element.
If the heating elements and seat harness tests OK, then a power supply problem
exists.
Using a digital volt meter, start at the source and trace back through all the
connectors and switch to determine where the power loss is occurring. Repair as
necessary.
If the seat heater fuse continues to blow, then a short or bad ground condition
exists in the power circuit.
If the vehicle fuse which has the heated seat T-tap connected to it continues to
blow, then the tap will need to be moved to another vehicle circuit.
