Heated seats

Bit unsure on this one the passenger side heated seat stopped working. I checked the relays and swapped them over now both seats work but now only give off a small amount of heat.

simply i dont get it any advice welcome.

Ben:

- first make sure the rheostat is good, or just bridge over it for testing purposes:

- then disconnect one seat at a time and see if the heating level increases on the remaining seat;

- if it does, then the main feed isnt up to handling the current, so replace the primary wire from rheostat to seats (pull out the seats, and lift the carpet, and splice in fresh 2-2.5 mm braided copper wire for the main heater feed to the two seats - after 8 or so years these tend to cook, develop a coating of oxide inside the insulation and then the resistance climbs, eventually when the oxide is hot, it arcs from strand to strand, etc)

- if it doesnt rise, then try another relay, or bridge over that and try again.

Whatever - you are trying to find oxide build up somewhere in the system. The likley culprits are (in the following order)

- rheostat;

- thick heater current wire delivering power to the matrix on the two seats;

- the heater panel within the seats.
