The heated seat system consists of the following components:
• Driver and passenger heated seat switches
• Driver and passenger seat back heater elements
• Driver and passenger seat cushion heater elements
• Driver and passenger seat back temperature sensors
• Driver seat module
• Driver door module
• Passenger door module
Do you know what a electronic module is ?
DTC B2425 or B2430
Circuit Description
The driver and passenger seat heaters are controlled by the driver seat module. Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the driver seat module through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the driver seat module in order to control the seat temperatures by regulating the current flow through the heater elements.
DTC Descriptors
This diagnostic procedure supports the following DTCs:
• DTC B2425 Driver Seat Heater Circuit
• DTC B2430 Passenger Seat Heater Circuit
Do you know what a DTC - diagnostic trouble code is.
you need to see if the seat is getting power to it at the connector plug if not trace back to see if switch is,if it is getting power you need to lookfurther at the seat itself,even check fuses but they are both probally on the same one
2003 surbarban driver seat and passenger windows have common fuse/breaker under hood in fuse panel. 50 Amp fuse upper left of box, marked mped this is a big fuse not the little ones.
There should be a connector under each seat which connects power to the heating element. It is likely either clipped to the seat or tucked under the carpeting. You'll almost definitely need to remove the seat to get easier access to it, though it should be possible to find/access it without removing it, just more difficult. Once you find it, disconnect it. You can use any multimeter with a continuity tester to test the circuit. First, check the DC voltage coming from the wires that come up from the floorboard. If you are getting voltage there, you will want to check continuity of the element itself by probing the two wires with the meter set to it's continuity testing selection. If there are more than two wires you will need to determine which is the common wire and which are the "live" wires. With the power disconnected you can test the element to figure this out easily. For example if your heated seat has three wires, test all three for continuity in pairs. If one wire always shows continuity no matter which other wires on the same plug you touch that should be common.
If the element tests good (in other words you find that all the circuits show continuity) and you are getting power from the plug that comes from the vehicle itself, you might need to check the resistance of the element. It is rare to have a bad element that still shows continuity, but it is possible that the resistance may have for some reason become lowered and the element therefore does not heat up.
Check with your local dealer or call me at 904-322-5150 my name is Adam. There may be an open recall that will solve your problem.. If so it can be fixed at no cost
sounds like a bad relay. Look in the owners manual or on the fusebox cover. It will not be a fuse, but a silvery looking box that pulls out. Youll have to check the documentation to see which one it is in your vehicle.
Sometimes it is under the seat in a Volvo.
check the relay under the seat, make sure it hasn't worked its way loose. if its still tight, the heater pad itself has probably checked out.
If its not the relay, and you want to save some $$, replace the drivers side with the P/S. 'F' the passenger :)
Check the fuse if you've changed the switch. 30 amp in position 44 (very bottom on the right) should be a green fuse. Fuse panel is behind a cover on the drivers side of the dashboard with the car door open. When you put the cover back on be carefull to align the three prongs that hold the cover in place with the slots that they go in.
