seatkid Posted July 22, 2013 Report Posted July 22, 2013 (edited) leeroy, it can be a number of things. If its a Ford 2.0 or 2.3 petrol engine, they have a deicing switch on the evaporator. If your pollen filter is blocked or the fan speed is very low, ice can build up on the evaporator and the deicing switch operate. The system may have been overfilled with refridgerant gas. In hot weather the pressure build up and the 3 way pressure switch (hi - normal - lo) may trip to protect the components. It may be a dicky pressure switch or dicky exterior temperature sensor or loose/shorting connectors/wiring. Edited July 22, 2013 by gregers sorted Quote
nexsuperne Posted July 23, 2013 Report Posted July 23, 2013 My moneys on the blocked pollen filter. Mine was black! Don't think it had ever been changed in the last 12 years.... does it run ok with recirc turned off? Quote
