I dunno. To replace the heater requires the upholstery shop to take the seat cover off and put it on again so maybe that price is not way off, but seems to me one of the first things they would check would be continuity in the heating element itself. Can’t that simply be done with a meter? So was the module bad too or just an extra part now? I understand they cannot return the module but if they just put the old one back in, now they’ll have one in stock to use for the next one that has a bad element instead.
