Andy52 Posted May 14, 2017 Share Posted May 14, 2017 Can anybody give me some tips on how to get my heater working please. The system is full of fresh water/antifreeze mix, but i have no heat from the heating system. Blower works fine, so i was wondering if there might be an airlock somewhere, if so how do i clear it? Do i go to the pipes that go through the bulkhead ? It is the zetec S 1.25 16 valve engine fitted with aircon. didnt have this problem with my previous mk4, which was running the same engine , but without the aircon. Any help would be much appreciated. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Luke4efc Posted May 15, 2017 Share Posted May 15, 2017 Possibly try a heater core flush? You'd be suprised at the amount of crap that will spill out of it, especially if it is an older car Quote Link to comment Share on other sites More sharing options...
Ad@m Posted May 15, 2017 Share Posted May 15, 2017 Probably the Heat Control Valve has seized, very common on the mk4/mk5. If you remove the partition where those 2 pipes go, you will see the heater control valve. Its that black thing the 2 pipes go in. By a new one on eBay, about £10. Just showing you this as an example, you need to make sure you buy the right one. http://www.ebay.co.uk/itm/HEATER-CONTROL-VALVE-7N2118495AC-FOR-FORD-FIESTA-KA-PUMA-TRANSIT-/122005724696?hash=item1c681b9e18:g:onIAAOSwOVpXUpVC 1 Quote Link to comment Share on other sites More sharing options...
MJNewton Posted May 15, 2017 Share Posted May 15, 2017 Note that a lot (most?) of the aftermarket heater control valves are very poor quality and don't last long (been there done that!) so do weigh up if they might represent a false economy against the genuine Ford component which costs ~£40. Of course, even the genuine article is not immune to failure but they usually give at least several years service. Quote Link to comment Share on other sites More sharing options...
Andy52 Posted May 22, 2017 Author Share Posted May 22, 2017 Thanks for the tips folks. I do have a spare control valve that came off my 96 mk4. Will give that a go, and flush through at the same time. Hopefully this will solve the problem. Never had a Ford before with a crappy heater, always relied on ford's for having good heaters. :-?

Andy52 Posted October 8, 2017 Author Share Posted October 8, 2017 Well i finally got around to sorting out the heater problem. Yes it was the heater control valve. Replaced with the genuine ford one from my previous fiesta, flushed the system through, and yay!!!! i now have a working heater. Its so nice to have warmth now the nights are getting colder. Kids appreciate it too. Thanks to everyone for the advice. greatly appreciated. 1 Quote Link to comment Share on other sites More sharing options...
