stef123 Posted August 12, 2011 Share Posted August 12, 2011 anyone care to shed some light on my little problemo? the heaters on my 2003 zetec will only work on full blast (setting number 4) nothing else on 1 to 3. help. If the dial is working then i would suggest that there is a fault with the resistor for the motor. http://www.fordpartsuk.com/shop/ford_focus_heater_resistor_1299.htm Quote Link to comment Share on other sites More sharing options...
johnH Posted August 12, 2011 Share Posted August 12, 2011 sounds like as stef123 says....resistor pack for the blowers Quote Link to comment Share on other sites More sharing options...
jocojohn Posted August 14, 2011 Share Posted August 14, 2011 Yes, you need a new resistor pack. Setting 4 bypasses the resistor pack totally, which is why that setting works. I've had this problem on both my Focuses Quote Link to comment Share on other sites More sharing options...
blueovalcraig Posted August 14, 2011 Share Posted August 14, 2011 One quick fix is to remove the resistor and solder a wire onto each end of the little diode. Quote Link to comment Share on other sites More sharing options...
