My Chief Navigator (& any random passengers that threaten to do so) are under strict instructions to NEVER kneel on the SLK seats.....
...and I've never been tempted to kneel on the seats to clean the inside of the rear windows & also
put My hand on the centre console, when leaning in to retrieve stuff from the car:
So luckily, mine are still both working
But My (2001) 406 Coupe heated drivers seat stopped working & I soldered the heater element lead
back together with a bit of heat shrink tubing, about 60,000 miles & many years ago & still working
The Peugeot heater seat element are covered in a cotton type coating and could see one of the brakes
due to a burn mark..!!
But the second brake was found using needle work type pins, on the end of My Fluke Meter leads,
to prick through the insulation, to find the 2nd location....!!
