Hi,

Just got myself a nice little Seicento Sporting. Great little car but it has a annoying problem with the heater, though the heating problem seems the opposite of others I've seen reported

For some reason the heater is always on. When you move the rotate heater dial is goes nearly all the way to full heat, but 'pings' back to around 2 o'clock location. When I move it round to the cold setting there is still heat coming out.

I'm guessing that this is being caused because the heater dial in really stuck in low-heat mode, rather than off (cold), but I'm not sure why. Would this be caused by the dial being broken, or by the cable being bent? From looking at the workshop manual, the diagnostic section just cover when the heater doesn't work and not this problem. I've love being unique

Any pointers greatly appreciated.

Thanks,

Jon

The embarrasing truth is probably that your cock has seized.

Don't despair. Fluffy at eurocarcare in Derby offers excellent counselling.

Yup, cock trouble.

Agree, speak to Fluffy.

Hi,

Thanks for that guys, sorry took so long read the replies I assumed I'd get a mail notifying me :bang:

I gather this is fairly easy to replace, so finger crossed.

Thanks again,

Jon

Hi,

Ok so from what I can figure out so far replacing the heater control valve (cock thingy) means I need would need to empty the coolant from the heater, or am I over complicating things?

Does look fairly straight forward as the heater unit is in the engine bay, which makes a nice change.

Or just let it come out (as it will).

Never done it, but I'm pretty sure you'll need to remove the heater matrix to get at the cock.

You will loose the coolant so budget and prepare to refill.

Cheers

Will do. Cheers for that.
