a few jimny issues

1) I think I've read that the heater air pipes under the dash can get kicked off but someone else will need to confirm that. This would limit the amount of hot air coming out of the vents.

My temp gauge sits at half once warm and doesn't move. I have the digital gauge and diagnostic box Martin has and it is running 10 deg warmer than normal @ present as I have a bit of mud in my rad but the gauge still sits at 1/2. I don't know why yours differs. Is it a single or double cam engine?

In respect of the coolant system having no pressure when hot, change your rad cap as they are set to allow coolant into the expansion tank at a set pressure and the spring on yours might be weak.

Is it using coolant?

2) Have you fiddled with the switch on the hand brake lever? I had the same on my SJ and it was that. It's prob under the plastic surround. I think Martin shows you how to get that off in one of his guides.

3) The wires to the switch in the gearbox and the switch can probably be found on top of the gearbox by crawling under the car and looking back up at the top of the gearbox. I've just come in from working on it but plan to look at my gearbox tomorrow so I'll try to remember to look for you.

I take it you've changed the bulb?

1. Not the hoses getting kicked off, its the plastic arms where the cables operating the flaps that get kicked. Therefore you loose the ability to move the vent flaps.

2. Yes - fiddle with the switch

3. Check the wires as they are vulnerable to damage underneath the car. I have had a switch fail as well.

I was nearly right, I knew I read something about something being kicked off!

Good luck then, I'm all out of suggestions I'm afraid then!

It could be a break in the insulation to the live wire going to the switch causing it to earth somewhere else to vaguely complete the circuit, hence the dimness. That will be a bugger to find though!
