I have an 08 with standard seats. I want to replace the mechanical seat with a 6 way power seat from a wrecked HHR.
Do all HHRs come pre wired with plug for a power seat, or will I have to figure out wiring colors and splice wires to get power?

 

Not much deciphering needed. Note it is on a breaker, not a fuse. Heated seats are a different question; requiring BCM programming.

 

@donbrew Hi. I have the same question as Robert. I have an LS with manual seats. I asked some questions on a coupe of the Facebook HHR groups about switching out my seats for power seats. The responses I received made it seem like the power seat connector pig-tail was just under the carpet. Easy, just pull the manual seats out, fish out the pig-tail from under the carpet, connect and install the power seats. So I picked up a nice set of power seats (just movement - no heat) and thought I could swap them in in an afternoon. It didn't work out that way. There are no pig-tails under the carpet. I pulled up my entire front carpet section trying to find where they might connect to?? I don't even see an empty power connector in the center console, under the window switches / HVAC controls or dash?? Your schematic makes sense, however I can not figure out where the "J313" junction / connector is?? I just can't relate what I'm seeing in the schematic to where it should be in the car?? Any idea where that "J313" is?? Thank you in advance for your help.

 

Same question, same answer.
There is a link in my sig to free shop manuals, everything included.

 

Thank you @donbrew So J313 is the connector under the seat. Ok, makes sense. Now I just have to find where the intermediate harness from J313 connects to the car??

 

It might be under the door sill.
