Factory heated seat switch

I snagged this switch a couple years ago and finally got around to installing it in my 98. I can't remember what year it came from though, but it's at least a 97-01. It seems like the switch doesn't quite fit right. I pulled the ashtray out and tried to pop it in, then noticed 2 little tabs underneath that don't seem to line up with anything on my console. I even tried carving out a spot for them to fit but it didn't seem to help. I'm not even sure it's compatible at this point. The latches at the very bottom don't grab like I figured they would.

I can't seem to find much info on the factory heated seat option. I guess most people aren't too concerned with luxuries.

I'll post some pics later.

Re: Factory heated seat switch





These are the tabs that I was referring to (the ones by my dirty thumb nail). I had to notch the console a little to get them to fit.





Dang this thing is dirtyyyy

Re: Factory heated seat switch

I put heated seats in my '00 that did not come with them.
Getting the ashtray out was a bear.
Putting the switches in was a piece of cake.
I am looking at my pictures of the install.
And my console appears to look different then yours.
I don't have any really good pictures showing it though.
But I have a theory.
So '99 was the first year of the heated seats in an XJ.
Thinking the console is slightly different in this area so they can put in the switch bezel in when the Jeep is optioned with heated seats.
I don't have a third parts picture posting thing, refuse to get one, but if you go here:

https://www.cherokeeforum.com/f59/wh...5/#post3563481

And look at Post# 91265 you can see the shot I do have.
I can't tell if the big slot is wider or longer then yours but don't think it is.
What I do see is that little notch at the 6 O'Clock position.
Where you modded your console.
So I think you are on the right track just need a little more work done there.

Re: Factory heated seat switch

Oh I have a question too.
What exactly are you doing?
Are you putting in factory heated seats from a '99 and up in?
Or are you trying to use the switches with aftermarket seat heaters?
Cause if the latter I am curious about that.
The crappy thing about heated seats in an XJ is that it is not a heating pad.
It is a wire actually sewn into the seat cover.
So sometimes the wire can be repaired when they stop working.
Sometimes not.
My guess is that when the heated seat covers were still available from Jeep that
instead of fixing the wire they replaced the whole seat cover.
So I have been wondering about using an aftermarket set up with factory switches.
See with factory heated seats it is more then wiring and switches.
On the passenger side power seat base there is something called a SHIM.
Seat Heater Interface Module. Also a relay.
On top of that incorporated in the wiring of the seat cover is what I believe they call a thermistor.
Best I can tell temperature sending unit of sorts.
Also so you know heated seat switches are always lit up.
The illumination for the symbols.
Even when the headlights are not on.

Re: Factory heated seat switch

I'll have to keep massaging things until it works. I really don't want to have to resort to screws underneath, but it's just not snapping in like I thought it would. And man, I really need to clean that thing up some before getting pictures. I didn't realize how gross it was.

So it's still summer in SC, so I haven't put a whole lot of thought into how I'm going to make the heaters work, bit my general plan was to use heated pads from Amazon and toss them under the seat skins. I don't want leather, but I've had heated seats before and they're really nice. Especially for soothing that aching back after a shit day of work.

I think I'm just going to use the switches to control a relay. Hopefully the heating pads come with a separate temperature control circuit. Like I said, I really haven't looked into it too hard yet, but I can't see it being that difficult to make it drive a relay.

Re: Factory heated seat switch

I kinda thought it was something like that.
Will be very interested in your progress.
Specifics too.
What heated pads you bought. Etc.
Please. LOL.
I had two ideas.
First one was what you want to do.
One was to use the whole aftermarket set up. Harness and all but just replace the switch with the factory one.
Second idea was to just use the heating pad itself with the factory wiring, switches, etc.
My seats work fine at the moment so I have not gotten around to playing with either of these ideas.

Hey Saudade, quote the post just above the one you quoted. You'll see that I did that and they don't work! I've been using forums for almost 20 years. Phot hosting sites have just gone terrible. I'll give Imgur a shot.

Re: Factory heated seat switch

Anyway

Ralph77, I looked into wiring diagrams and found something really neat. I was wondering how to go about making hi/low work on this thing. It's pretty simple. In high, wire them (back and seat heaters) to come on in parallel. That way you get full voltage in each branch circuit. Since their resistances are both equal, you get the same (higher) current for each pad. However, to get LO you would wire them in series. Since they are getting half voltage each, they also get half of the current. That also means that each heater pad (in series) is only getting 25% of the power (watts) they would in parallel.



I'll get it all figured out and make it simple. And probably before it starts getting cold. I hate a cold butt.

Re: Factory heated seat switch

OK.
Thinking I should have told you one more thing.
Of all the things I am bad at electrical tops the list.
So all of what you wrote above went right over my head. LOL.
But I have a friend who is really good with the stuff so I will show him what you figured out.
He will most likely understand it and explain it to me. MLOL.
If this could get figured out it would be awesome.

I am big on the factory look. But underneath where you can't see don't really care.
Example would be my "factory fog lights".
My Jeep did not come with them. I bought aftermarket factory fogs. Used a factory switch. But wired them up like aftermarket. Even grabbed connectors for the fogs off a headlight harness. So it looks factory up front, in the passenger compartment, and is more plug and play. Which I am OK with.

Like I said the factory heated seats are a bad design IMO.
I have scoffed extra parts just to try ways to figure something out.
I have an extra wiring harness for the heated seats.
I also have pig tails for the switches.
I even have extra heated seats that are in really crappy condition.

Oh I forgot to tell you my other 2 bad ideas.
I want to try and find a heating pad from a WJ. I know the connector to my existing wiring harness is probably not the same but would like to confirm this for sure.
Also I think ZJ could have heated seats. Curious as to how those are set up.

And last make my own heating pad. Take the wiring out of one of the crappy heated seats and use the thermistor and connectors. Would like to replace the wiring but can't seem to get a handle on what kind of wire is used in heated seats. Figure it is not just some thin gauge wire but......

zluster here is also putting heated seats in his MJ. But he replaced the interior in that with a newer Jeep interior so I am also curious as to how he plans to do his install.

Re: Factory heated seat switch

Oh forgot to ask.
Did you manage to get the switch bezel to "lock in place"?

No worries. Unless you pay for PB, they tightly restrict what you can do. Oddly, clicking the blank photo takes you to the page with the pic. I abandoned PB a while back

Flickr has a similar feature.
