Hi all,

Having a weird problem with my defender TD5. Like normal the engine takes ages to heat up but even when fully hot the hot air only works intermittently. It just blasts out cold air.

The problem is worse when on motorway - just has a 3 hour run back to notts and whilst at 80mph it just pumped out cold air even with engine at normal running temp.

It does randomly start working for periods of around 10 min.... but even then its only a bit warm not the propper temp.

Does anyone have any idea whats going on here :confused:

Many thanks!

Do you have an airscoop? If so, thats the issue. There's too much cold air being pushed in.

Or at least thats what I put mine down to. Sat still it gets very toasty, moving at 60 its cold as anything.
