Hi there,

Apologies to those who may feel like this is groundhog day but I was hoping to get some input on a problem I've just encountered in my 2005 997 C2S. It has electric seats and all has been fine since I got hold of the car a few months back. Last week, whilst driving, my passenger reported that they were unable to recline/upright the seat. Forwards/backwards, up/down and the lumbar were all fine.

I took a look later int he day and found that the recline function had worked but the uprighting was not. As a result I currently have an overly-reclined passenger seat and cannot upright it. All other electric seat functions on both sides are operating OK, it is just passenger side uprighting that doesn't respond.

I've looked under the seat and all appears to be in order. I assume the motor that reclines is the same one that uprights but the cause of not being able to go one way is a mystery. Any support or signposting would be hugely appreciated.

many thanks,

DP.

My guess would be a faulty switch .. you would need to start checking the wiring from the switch to the control unit .. that's basically seat out a wiring diagram and a continuity check .

As all the other functions are ok then that rules out any power supply problems .

LV is the motor , it can be power probed to operate but you would need to do this when disconnected to the control unit .

thanks. removing the seat feels like a potential can of worms! Do you know if there's a way of manually uprighting the seat in the meantime?

Its an electric motor with no manual option im afraid .

If it was me i would probably pull off the switch cover and just try to press the switch direct .. sometimes it's just this cover that breaks .

thanks, I just tried that but everything's intact. Upon removal, I can still recline the seat with the little white switch but a forward movement yields nothing. Very frustrating, passenger seat now as good as unusable.
