I have a 99 Deville which does not have mem seats. My power window master switch needs to be replaced so Ifigure I'll getone with a memory seat option. I know how to install themaster switch but my question is do I need tohave extra wiring installed or is there already wiring present that just needs plugged in. I can take the door panel off to get to it. Ijust need to know ifthe wiring is there and where it is.

 

Memory seat is not plug and play,but if you have a couple grand I'm sure you can add it.To replace switch gentle pry off door handle bezel replace switch.

 

No I have a 99 Deville but are the wires present anywhere to plug into the mem seat module or do they have to be installed? Or,do I have to get another power seat control module that plugs directly into the mem seat module?

 

Wiring not there,several modules, memory power seat risers, all required but not there. If you have deep pockets it can be done.

 

Well thanks for the info. I now know not to even attempt it on my own and that it's not worth the cost either.
