Thanks - I'll try a little disassembly and check the sensor. Getting a similar NTC would probably not be a problem. I don't suspect the heater core (yet) - no leaks, and it is able to produce nice, hot air (within the first hour :) - also, the thermometer indicates no problems, it has never been above center. regards Per "Andy Hookins" <andrew.hookinsnopsamamnopsamodata.co.uk> skrev i en meddelelse news:uump9as85vtm2anopsam.supernews.com... > I had the same problem but now it seems a lot better: > Have you taken the temp sensor out of the dashboard > and blown out all the dust that collects in there?
