Posting on behalf of a friend here, so all I know is, he has a Citreon Xsara 1.4CX (52) he cannot switch off, turn down, or adjust the heating controls in his car, and it is stuck on cold. anyone had this type of problem before??
Never had that on a Xsara before, I'd guess the control panel's had it but the only common problem with Xsaras is the fan not working at all (due to a dumb design in the ignition switch)
