trim,,,, se sse sle ssei

Where in Mass, I'm in Enfield and have done this type of thing before. If you want to do it factory, then it'* not bad. If you want to do something along the lines of aftermarket it'* even easier.

Here'* how I added them on the 97 where no provisions were in place.

trim level of your car,,,, se sse sle ssei

My 2000 ssei didn't come with heated seats. The dealer contacted a place that installs such things for dealers only. Since than, there are many aftermarket, DIY heated seat kits. IIRC, they also have heated seat kits for cloth seats. 99% of the time, heated seats are only an option on a vehicle with leather. The leather absorbs some of the heat, and the thickness prevents you from feeling the elements. It'* been a few years since I have searched, do an online search and you should come up with a few options. The seats need to have the upholstry taken off to the point you can get the elements in and wiring run.
