Hi all

I have an R Reg MK4 which is my baby (don't laugh!). I've recently changed jobs and considered changing cars because I now have a 35 mile motorway commute as opposed to a 2.5 mile town commute, but decided to put a bit of money into the Fiesta instead whilst I complete my probation and decide whether to relocate.

It's had a full service, cam belt change, new front tyres and a new exhaust (the latter wasn't part of the original plan, just typical timing). Where I'm struggling is the heating system.

I know that there's a common fault with the valve. So replaced that. Well, I bought it and the garage put it in when they were doing the cam belt/coolant. It felt like it worked for a few minutes and then nothing, back to hot air. As you can imagine this isn't pleasant when you're spending an hour on the motorway. I did ask the garage a couple of years ago to tell me why the heater was always blowing warm - they said it was normal - so I can't just go "here fix this". It was a family member who suggested changing the heater valve.

What is weird is if I switch the fan on, it sounds like there's something stuck in the fan whirring around with it. Like a bit of paper brushing against casing or something. I'm probably going to go under the bonnet tomorrow with the help of my trusty Haynes manual.

Thing is I don't really know what I'm looking for so will just have to rummage for things that look "off". Does anybody have suggestions of what the issue might be?

TIA

 

Did you fit a genuine Ford heater control valve? Aftermarket ones are known to be shite and either leak or blow just hot, as yours is doing.

 

No it was aftermarket.

I guess a trip to a Ford dealer is in order - any other parts I should consider getting?

 

Change that for now as they are the culprit 95% of the time!!
