Howdie, now that the weather is getting better I thought I would try finding what's wrong with this heater. It's a basic Jimny so no aircon in it, but I am finding the air being pushed out of the system is pretty meek and it's not really hot at all.
I get no heat until the engine heats up a fair bit (takes a good 15miles and the temp gauge to around 1/3 high), and frequently have problems clearing condensation in the car. All it takes is a cold night and I'm stuck for 15minutes trying to clear up the car windows, which are still fairly foggy after that!
Any advice on what I should be looking at to narrow down and fix the problem. The control arms for the heater look all in place from what I can tell.
Leave the engine running for about 15 mins see if temp guage rises check top rad hose it should be hot, if it is only warm it will be the thermostat, had this with mine changed thermostat, problem solved, simples
Did you manage to fix it?
if not i had problem with this i tried everything nothing was workin i thort maybe there was cracks as i found radweld and my thermo was in wrong way round i started all over again tryin to figure out what was wrong i had driven 35 miles and it was freezing so when i got home i decided to look i know silly idea taking off rad cap but it wasnt until i realised there was no pressure nuffin squirted out so i went online it was like 10-15 for a new one so off i went down scrappys they had no jimnys no vitaras just one swift lucky enough it fitted £ 1.50 i took it for test drive 10 miles down the road i decided to try again and the oil shot up everywhere now my jimny is nice and toasty try it it may be that
hope it works
