heating

my td5 does not get very warm inside and i have noticed that the aircon radiator cooling fan is working all the time. i have pulled the relay out.the car still doesn,t get warm until i have done about 15 miles.help!

The aircon fan is controlled by the BCM so if because you have overheated the engine (or the ECU thinks you have) it sets a fault which causes the aircon fan to run constantly with the ignition on.
To reset you will need to see a dealer or indi with 'testbook' or someone with similar kit.

thankyou very much i know someone with equipment to fix it.
