Drivers electric seat won't work
 

My 2006 Grand Voyager's seat has stopped working. Where is the fuse ? Is there another possibility ? I have checked leads etc., buit can't see anything loose.

Maybe this will help. It's from the 2001-2007 Dodge Caravan Service Repair Manual:

DIAGNOSIS AND TESTING
POWER SEAT SYSTEM
Following are tests that will help to diagnose the
hard wired components and circuits of the power seat
system. However, if the vehicle is also equipped with
the optional memory system, these tests may not
prove conclusive in the diagnosis of the driver side
power seat. In order to obtain conclusive testing of
the driver side power seat with the memory system
option, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules
that provide inputs to, or receive outputs from
the memory system components must be checked,
(Refer to 8 - ELECTRICAL/POWER SEATS - DIAGNOSIS
AND TESTING).
WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS. BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MINUTES
FOR THE SYSTEM CAPACITOR TO DISCHARGE
BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
(1) If either power seat is completely inoperable,
check the power seat circuit breaker, located under
the trailing edge of the driver side power seat. If the
power seat circuit breaker is OK, continue to the
next step.
(2) Check for proper battery and ground connections
at the power seat switch and/or memory seat
module. Repair any wiring as necessary.
(3) Check the power seat system wire harness connections
and pins to ensure proper circuit continuity
and ground paths.
