Thread: Help needed with Air con Problem

try a few of these

1. switch the system on with the engine not running. Wiggle/remove the relays and plugs in the compartment under the pax seat to determine which relay turns each bit on and off.
2. buy some electrical cleaner and clean all the plugs and sockets for verdigrease.
3. check you have power to the fan clutch when the system turns on and off using the temp switch
4. check all the fuses in the various locations in pax compartment and batterybay. Use a multimeter don't just look at them. spray all fuses with contact cleaner when re assembling.
5. if you do manage to get it goint check the sight glasses on the receiver dryer for bubbles.

if all else fails talk to the guys in redcliffe.

Read yesterday of a fuse for the lower fan speeds, does the fastest seting work?(Rave Disco2,might be the same).

Ok will try


And not taking it to MR after what they did to Insor old Disco never taking a car there .

Ok after checking all the fuses and the relays. Still not found the reason it does not work. There is no clicking coming from the relays when you swtich the fan AC on and off. But there is power going to the fan as i unpluged the plug to the fan and then put a multi meter on it and turned the dial on the AC and it showed power coming though.

Know a far bit about landies but being a pom this is my first defender with AC and don't know anything about AC on the defenders. So a bit lost really

Anymore surgesting of where i shoud check

Cheers
Ali

Ok panic over

Started taping things with the end of the racket and found one of the relays in the battery box to be the problem

Thanks for all your help

That is the first time I have heard any bad about MR.What Happened?
John ( disco 44 )

Same thing happened to me about 6 months ago, found out the black regulator in the battery bay under passenger seat is where the problem is, after a lot of fiddling with the wire plug that fits into the top, approx 6 wires from memory, was not connecting properly, i jiggled it a couple of times and hey presto aircon works. I think it needs the plug with the wires in it replacing as they get a bit stretched and dont want to connect properly, mine had a burn mark on the plastic where the red wire enters the plug.
give it a go.
if i remember tomorrow i will post up a couple of pics for you.
