heated seat switch

[Brian H]

anyone have a pt # for the HSS's? Mine are aftermarket and i'm going to relocate to the proper position. Thanx ahead of time.

Sorry, no part number, but you ought to do some extensive research before heading down this path...

Customizing the control circuit will be necessary, along with the wiring harness. The only way to put the switches in the door panels and have them look right is to replace the door panels with some from a car with heated seats.

Absolutely correct, a lot of the aftermarket stuff seems to be switched by grounds, as opposed to a 12v+ switch. You should be able to make it happen with some relays, it is possible that the car is pre wired for those switches as well, you would have to pull the door panels off to verify that.

That said.... I have a set of door panels with the switches in them, if you are interested.

They are not pre-wired. Gotta add in the wiring piggy-backed to the OEM harness.

Custom controls will be difficult for full functionality. They are momentary switches and have some logic that would be hard to duplicate with simple relay circuits. Only way I can think of to do it would have a single setting instead of high/low selection.

Latching relays are your friend. Same deal as the aftermarket Webasto moonroof I had in my sport. I used a bank of relays to make a OEM switch operate it and retain an OEM appearance.

Not sure how you'll make the OEM switches work the latching relays. Press the high side of the button and it latches the relay to turn on the high element and also turns off the low element if it is on. Press the low side and it latches the relay to turn on the low element and also turns off the high element if it is on... That part shouldn't be too difficult.

Here's the problem: IF the high heat is already on and you press the high button again, it should turn off the heated seat. Same with the low selection, if it is already on and you press the low side switch again it should turn off the heated seat.

It'll take more than a pair per door to make it work.

Very interested in how this works, need it for another project. Can you draw up a schematic?

I could, I would need to sit down with the seat heaters in question and a set of switches, otherwise it is guess work at best.

When you hijackers get it figgered out, let me no. Then we'll talk about the door panels(Spectra), and the install (Fordnut). Keep me posted,........you hijackers! (haha)
