OK, I went to the EPC. There is a 'Mixed Air Temp" sensor on the right side of the main HVAC unit behind the dash. I do not know the best way to get to this, either remove the glovebox/RHS airbag (on LHD cars) or maybe through the top after the dash cover is removed. I guess this could be bad or just a bit off. I do not yet know if there is a way it could be better insulated or what, but you may want to see if you could pick one up in a JY just to see if it behaves differently. 9k '93-'98 part number 43 18 788. This was a running change in mid '92 from 96 29 395 which was from '90-'92. Let us know what you learn. KeithG KeithG wrote: > I'm watching this thread as well.
