how is the thermostat???? and how new is the coolant and have you everdone a radiator flush and pressure test5 minutes???? not much warmth coming out of mine after 20
good un....... heater core could be plugged or got air in itMake sure the heater's actually working for a start. Standard heaters are reasonably good when they work
Funnily enough I had the same idea myself!My trick is a small 240v fan heater sat on the cubby box with an extension running to the garage on a timer switch. 20 mins before I set off for work, timer kicks in. No ice on windows and nice and toasty, set off to work, by the time the cab has cooled down the engine is warm and I can use the heater.
