Drivers Heated seat turning off

[grahamfromoldham]

My car has suffered with the driver's heated seat shutting down intermittently for over 15 months with several trips to the dealers. They have replaced the heated pads and wiring last year which stayed ok for a few weeks but started again. I took it in a couple of weeks ago and they're still not convinced anything is wrong as it wouldn't fault under their supervision. Because a fault code (B2425 I think) was logged they decided to replace the heated pads AGAIN. The day they were returning the car to me, it went faulty again which proves it isn't the heated pads. They then went and replaced the control module but still again it is faulting. The dealer has been in touch with Vauxhall Technical who asked for the current software the car uses which the dealer provided. They said mine is up to date and that the seat is operating normally (bull****). They have returned the car to me today, still faulty in my eyes but I have drawn a blank. In the meantime I have contacted Vauxhall customer services and spoke to someone 'high up' who is looking into the matter for me but to be honest I don't hold out much hope.
The passenger seat has always worked fine, the lights on the button stay illuminated permanently just like my driver's button used to do and the heat seems to be regulated fine. I am banging my head against a brick wall and they seem to be washing their hands of me by fobbing me off saying its working fine. If that's the case, then why did they feel the need to replace the heated pads (cost £490) and the control module.
