1997 gu nissan patrol air con problems

HI Vince,
how are ya mate,i manage a aircon company and and it sounds like you could have a number of different problems.not knowing where you live you should ring the VASA assoc and find your nearest one and they should give you more help.

cheers steve

here's some suggestions [had similar issuesin my GU]:

1) I wonder if it is the sensors on the bottom radiator tank. Highly likely.

2) Are the cooling fins completely free of dirt & junk? My "clean" rad had 750 grams of very fine bulldust etc in it.

3) ask the question on the patrol forum, which is

4) if in Adelaide try Highgate Air in the CBD

Cheers

I had a similar problem with my Mav. I fixed it by cleaning the dirt out of the condensor core, the system needs it to be free of blockages or it just freezes up and wont flow.

more info needed so we can help . What model GU . is it ST or Ti , does it have climate control ? have you been off road ?

vince76, I've got a '98 Patrol petrol wagon too and it did exactly the same thing during a Pilbara summer. Very boring indeed.

I took it to some mob in Karratha who let a small amount of refrigerant out of the system. He assured me they switch themsleves off because they get overpressurised. Still did it, but to a lesser extent. I'm still not convinced about this.

I also took the radiator out and thoroughly cleaned it to get rid of spinifex, dust build up etc. It was surprising how much crud could still be washed away after blowing it out. Don't forget to clean the aircon unit too. Touch wood, it seems fine now.
