Default Heated seats

I know this question was posted before by someone else , but I'd like to ask again. On a car with the heated seats option, there are two buttons by the lower dash for on and off for each seat.
I don't have the heated seat option, but when I took apart my dash I found the wiring and button switches there, just without the buttons on the wood dash section. My next idea is to check the actual seats. Anyone know if you just add the switches if the seats will heat?

You can try just shorting the two wire ends together and see if your seat heats up. That's all the swithc does is put the two ends together. Try it and let us know.

I was wondering the same thing. Please let us know what happens.

I took the unit apart and found the two relays that would turn on the seats, but not being very experienced with electrical things I didn't know what the make the contacts with. It's actually very easy to get the unit out if anyone else wants to mess with it. I'll write more detailed directions if anyone is interested.

Relays?

Where did you find relays? Just wondering because I wouldn't think there should be any relays in the console area. Maybe in the engine compartment or up under the dash.

Try just taking the two wire connectors (Called Spade Connectors) that would slip over the Spade Lug on the switch and touch them together.

Usually the way a Spade Connector is made you can sort of force the two connectors together so they will stay connected.

A switch works the same way, all it does is mechanically connect the two wires together when you throw the switch on.

Now I'm even more assured I don't have any electrical knowledge ;-)
I guess I used relay in the wrong sense, I meant that when you look inside the box that would normally hold the button you push in and out there are 2 silver contacts on a PCB board. I'm assuming those are the points I would touch to make the power go to the seats. The thing is I don't know what to touch them with? two pieces of metal? Am I going to get shocked or something? LOL.

I don't understand why they didn't just use wires....probably not expensive enough:-)

You can use a pair of needle nose pliers. Just put one one side on each terminal. Squeeze to hold, don't squeeze to bend!

You can also use a rubberband looped around the handle of the needle nose to keep the tension on the terminals.

You won't get shocked. It's only 12 volts. Based on your body resistance divided by the voltage (I=E/R) you can't draw enough current to be harmful. But as with any electrical contact, if you have wet or moistness at the point of contact your resistance is lowered.
