Cold heater..... which technically means it's not a heater

Left the disco running for 10 mins this morning to warm it up before I went out. Gets in and it's still -9 inside. Fair enough, probably not long enough to warm up. Anyway, I'm on my way to take the wife to work, queueing trffic for a good 15mins, so I left it in neutral and held it at 2500-3000rpm for a while to warm it up. Drove the rest of the journey to her work and back home again with still no warm air coming out of the blower (temp gauge showing middle). Pulled on the drive and poppped the bonnet, engine warm, rad warm, hoses pressurised as normal.... yet the blower blows air cold enough to faze a polar bear?

The thermostat must be open or the rad wouldn't be warm, right?

Any ideas?

There's a thread above this on cool heaters http://www.landyzone.co.uk/lz/f8/help-heater-hot-when-moving-but-cold-when-traffic-126169.html

There have been lots of queries with this problem.
Almost always fixed by changing the thermostat.
Cheap and easy to do.
Always start with the easiest thing to do.
Sorted out me completely.Heat in cab within a couple of minutes and eventually tropical.Worth a try
