Hi all

Last year my drivers heated seat stopped working. I would push the heat button and it would come on for around 10 seconds and then switch itself off. I checked fuses, connections and carried out some continuity testing but couldn’t find a fault.

Last winter I jumped into Sylvia, turned the key and was greeted with a resounding “clonk”. A quick jump start, clear any codes thrown up and I was back on the road. Last week I twice went to start up only to find that the battery was dead.

On Sunday I bit the bullet and bought a new battery. Fitted without incident and Sylvia a happy Rangy once again. Yesterday I inadvertently pushed the drivers heated seat button only for it to come on and heat up without issue. I think that because I disconnected the battery everything on the car reset? I didn’t do a hard reset by touching the positive and negative battery leads together but there was a 10 minute period where there was no battery on the car.

If you are having problems with your heated seat I would try disconnecting and reconnecting your battery before you spend hours looking for broken wires etc.

it appears nowadays that most things like phones, PC's and now cars have to have a 'reboot' to settle problematic electronics..

glad its all sorted Jim..  ... - .- -.

Or is the seat ECU clever enough to know that the failing battery drops the current to a dangerous level so switches the seat heater off...!!

Did the passenger one work OK..??

What about the heated steering wheel..?

Heated steering wheel and passenger seat worked fine so not really sure what was reset when I put the new battery on?

A Fattie seems to be like everything else with a computer, when in doubt, pull the plug out, amazing the problems that solves.
