Hi all, managed to change the sparkplugs on the weekend (giddy-up what a job) went for a drive and everything works fine. Got into the car this morning and driving to work when the heater came on at full temp. Managed to get it cold by turning on the A/C at 17 degrees and it stayed cool when A/C turned off. Increased temp to 18 and the full heat came back on???? For some unknown reason I have no temp control anymore, does anyone have any ideas what I should start looking.
