a few jimny issues

Hi all

i have a few issues with my jimny which ive had for a year and hope you can help

1. Heater ive had this problem where its just blowing warmish air out ive replaced the therostat flushed the system out.
While driving on a flat normal road gauge goes to 1/2 perfect but when traveling down hill drops to 1/4 even 0 then goes back up when driving again theres no pressure in the system even after a long drive take the cap off nothing
ive checked for leaks in the oil and for any leaks in the system and nothing any ideas

2. hadbrake
when i take the hand brake off the light dimms dosent go off completely (sometimes it will) but most of the time it wont ive tried disconecting from the hand brake but still stays on checked the levels all ok any ideas

3. reverse light dont work looked under bonnet and and can see the wires comming out to the gearbox but thats it its been diconnected but cant see any wires on where it reconnects to in the engine bay does any one have a pic on where they reconnect to

thanks all hope you guys can help me

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.

hi kirkynut

1. i bought a new rad cap today as the other had to splits in it but the problem is still there ive checked all the rad pipes the top ones are nice and warm inc the heater pipes but the bottom rad pipe is stone cold im out of ideas on this one


2. yes ive had the hand brake cowel off unplugged the switch but it just stays dim but berfore when i was running the car looking at the coolant system it was off

switched the engine off and on and the light was back on again

3. the wire comes from the gear box ends in a terminal clip but thats it ive looked on the wiring loom at back of engine and cant see any where where it plugs into

can you post pics on this site?

yes theres a box to add attachments when you write a reply.
