the air blowers on my ford puma blows out hot air constantly and cant be adjusted how can i fix this problem, the seting 123 works but not the cold - hot setting
ou will most probably find its a heater controll valve at fault located under the bonnet by the bulkhead if you unplug the two pin plug and put a 501 type builb across pins and start car put heat on half way and blower on builb should flash slowly if it does poss valve fault if it doesnt poss switch fault
