04 1.3 Heater only blowing out hot air - fordgirl
The heater in my car is only blowing out hot air. Even with the control turned off and dial turned to cold.

There was an intermittent problem with the heater not working at all last year, but that seemed to be just a poor connection with the wiring.

Anyone have any ideas?

Can be a few different things; but the heater control valve in the heater feed hoses [under plastic cover on the bulkhead at the back of the engine] has a reputation for sticking.

start at the valve (two heater pipes at rear of engine going towards the dash, the valve is behind the plastic panel) very common but the control panel packs up also
