dtulip8 Posted October 19, 2019 Share Posted October 19, 2019 Just in time for winter, the heater has stopped blowing hot air! What do I need to be checking to eliminate all potential issues? I'm wondering if it could be an airlock as I did top coolant up a few weeks ago, but the engine runs at normal temperature.Thanks in advance guys!

TomsFocus Posted October 19, 2019 Share Posted October 19, 2019 How much coolant did you have to add? Unless it was very low, literally the bottom of the bottle, it shouldn't have sucked any air in. If you touch the metal pipes to the left of the clutch pedal once the engines up to temperature, do they feel hot? 2 Quote Link to comment Share on other sites More sharing options...
dtulip8 Posted October 19, 2019 Author Share Posted October 19, 2019 Yeah, just ran the engine up to temp with coolant cap off, all pipes feel hot both the ones by the clutch pedal (May have got a bit burnt there 😂) and in the engine bay. Assuming it’s probably the switch that’s busted? Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted October 19, 2019 Share Posted October 19, 2019 Lol, you were only meant to touch them, not hold them. I assume it's just manual temp control on yours, not electronic climate? If so, the diverter flaps are cable operated - ie, twist the dial, dial pulls cable, cable pulls flap open to let hot air through. Most likely to be a damaged cable but you'll have to remove the dash panel to have a look either way. 3 Quote Link to comment Share on other sites More sharing options...

Yeah just twiddly dials for me, will pop off the dash at some point and have a gander. Quote Link to comment Share on other sites More sharing options...
JONATHAN_11_80 Posted October 19, 2019 Share Posted October 19, 2019 I had this on my focus its the heater cable. When you turn the heater knob it pulls a cable which it turn opens the heater flap to let air through the heater matrix. I would pull the radio out and watch the cable as you turn the knob. I bodged mine with a cable tie. Worst case is a new cable which is £30 from Ford. 2 Quote Link to comment Share on other sites More sharing options...
dtulip8 Posted October 19, 2019 Author Share Posted October 19, 2019 Yeah that’s what I’ll do, only problem is getting the radio out as it’s aftermarket. Quote Link to comment Share on other sites More sharing options...

dtulip8 Posted November 4, 2019 Author Share Posted November 4, 2019 Dash disassembled, cable appears to be working fine but disappears down somewhere. I have attached a video: Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted November 5, 2019 Share Posted November 5, 2019 Hmm, the flap may be broken inside the box then, not sure if you can access that without removing the dash! 1 Quote Link to comment Share on other sites More sharing options...
dtulip8 Posted November 5, 2019 Author Share Posted November 5, 2019 Oh dear, probably won’t bother getting it fixed then as I’ll probably be getting a new car in May. Out of curiosity, what causes it to break? Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted November 5, 2019 Share Posted November 5, 2019 Heat cycles make the plastic brittle until eventually something snaps. If you can get access to it, you might be able to manually turn it to hot only instead which might be more useful for winter. 1 Quote Link to comment Share on other sites More sharing options...
dtulip8 Posted November 5, 2019 Author Share Posted November 5, 2019 I’ll take it to the garage to see what they think, I do t have the tools to be able to remove the dash. Another crap piece of design from Ford! Quote Link to comment Share on other sites More sharing options...

Another crap piece of design from Ford! Even at a garage you're looking at 6 hours to remove the dash so not worth doing. If you can feel your way to the other end of the cable that might help, I haven't done it on a Focus so not sure exactly where the flap is. This isn't a Ford design flaw though, manual heater boxes are pretty much the same in every car. I lost one of the flaps in the A3 last year and have seen plenty fail on other cars too. 2 Quote Link to comment Share on other sites More sharing options...
dtulip8 Posted November 5, 2019 Author Share Posted November 5, 2019 Fair enough then, I shan’t slate Ford for this one then. I’ll try and see if I can reach in there but my hands are massive so might be difficult! Quote Link to comment Share on other sites More sharing options...
dtulip8 Posted November 5, 2019 Author Share Posted November 5, 2019 I’ve even pulled the panels in the footwell out and cannot see where on Earth the cable goes. Think I’ll just have to wear a coat this winter! Quote Link to comment Share on other sites More sharing options...

Think I’ll just have to wear a coat this winter! The part of the box which houses the diverter flap is right at the bottom/rear, up against the bulkhead. There's no possible way to get to it without taking the ENTIRE dashboard out (I know because it did it a year or 2 ago. It only needs basic tools but there is LOTS of fiddly stuff, screws, bolts, looms and if you don't get the various looms routed correctly when you put it back together you might find a connector won't reach where it needs to, then it's back to pulling the dashboard out again. You'd even need to remove the steering wheel and the top part of the steering column. As I said, doable with basic tools but set aside 2/2.5 days to do it yourself. As you'd expect you'll be a bit quicker putting stuff back together. 2 1 Quote Link to comment Share on other sites More sharing options...

Sell or PX yours as 'no heating' for a few hundred too. Depends how much you use the car really. I find it really difficult to drive with cold hands myself, might just be me though lol. 1 Quote Link to comment Share on other sites More sharing options...

Can't remember what car it was now, but they were simpler then and still a pig of a job. When the same thing happened on another car I just altered the hoses to bypass the matrix and wore an extra jumper until I got rid of the car!😀 1 1 Quote Link to comment Share on other sites More sharing options...

That might be a tempting proposition tbh! I dunno how much I’d get for it with no heating though. I don’t use it a massive amount at uni, but it is useful for the odd trip out and when I go home. 1 hour ago, Eric Bloodaxe said: What a nightmare!

dtulip8 Posted November 8, 2019 Author Share Posted November 8, 2019 Have contacted a few of these companies that part cars out to see what they’ll offer. Might look around copart or somewhere and try and pick up a 1.8 or 2.0 either in a higher spec or slightly newer. Some of these Cat N cars have very minor damage I could probably fix myself, so we’ll see. Gutted as I have a bit of an attachment to the car, as it was my first 😢 Quote Link to comment Share on other sites More sharing options...

Gutted as I have a bit of an attachment to the car, as it was my first 😢 Honestly, stick it on FB Marketplace or Gumtree at a reasonable price and you'll be surprised how quickly it'll sell even without heating, I doubt breakers will offer more than scrap (around £200). Cheap cars with MOT are easy to sell regardless of condition! I would warn against buying cat N cars though (as I own one! ) they're virtually worthless and impossible to sell as people believe they're dangerous. They're also never perfect again which is annoying if you're a perfectionist! If you're just looking for a super cheap A-B car for 6 months, some Cat N cars don't even need fixing, a dent in the rear quarter can easily write off a car as it takes time & skill to repair, but isn't an MOT failure so you can just stick it through MOT and be back on the road! Also bear in mind some insurers charge more for cat N cars. 2 Quote Link to comment Share on other sites More sharing options...

I might just whack it on for around £500ish if I do decide to get rid, honestly not fussed on resale of the Cat N as like you say I just need an ultra cheap car for 6 months.
