Does the compressor turn on? Does the cooling fan in front of the condenser run? What doesn't work?

I'm with Dave, it's the flux capacitor that needs recharging, I could sell you some plutonium but you would need to pick it up as I have been having problems with shippers lately.



J/K we need a little more info to be able to help it could just be a stupid fuse.

Turn on the AC, open da hood and look at the AC compressor (from the front it is on the top left of the engine), the center section of the clutch should be turning. There is also a electric fan that should come on, it is infront of the radiator and you can see it by looking through the grill it too should be spinning. What exactly isn't happening? Does it blow air, is the air cold?

Not on a 97. If the electric fan is spinning you are about to experience a thermo nuclear meltdown. Mike is correct referencing the center of the A/C compressor.

Did it suddenly stop blowing cold air? or did it slowly go bad? Might need a recharge (R-12? R-134? Don't have A/C, dont know what it takes)

Dan, Here's some pics of where your compressor is in your engine. Look for insulated pipes going to and from it. The front (viewed from standing in front of your truck) of the compressor has a pulley that turns all the time with the serpentine belt also turning your alternator, steering pump, etc. In the center part of this pulley does NOT turn if the A/C is off. It should turn while the A/C is on. Turn your A/C temp control to cold and turn the A/C fan on. Go in front and look at the center of teh A/C compressor pulley; it should be turning. If it is not turning, you can check the fuse on the bulkhead (firewall). At least on the '94's is on there. Not sure about the '97's.

Also, I'd love to know why an air conditioning condenser fan doesn't have to be turning. There is no other application* of this type of heat exchanger where this fan is not supposed to be on, including all the other Land Rover models of 1997.

*Except this one:

Unplugged compressor = $0
All new a/c installed $2500+

or any thing in between.

Dan--

If you feel like driving to LA next week I will be in Brentwood for a few days (Thursday - Sunday) and I would be happy to take a look at it with you before you take it to the shop.

Tom

Aw~
thanks, fellas...and thank you Tom for such a kind gesture........but i got it figured out...

really poor design flaw:

on the 97, the compressor "pipe"..the one that gets cold and wet with condensation.....well...the sucked had a hot tube sitting against it....simply melted the pipe! wow....

so the local radiator shop simply welded it back......kinda cheesy....but it worked....and filled my freon up......all for $100.....good deal??

happy and cooler,

-dan

glad you got a cheap and easy fix to your problem.

to answer the question on the fan, the 97 system (and I think 95 too) is fitted with a tri-function pressure switch. At 2 atm, the switch turns off the compressor because pressue is too low. At 30 atm, the swtich turns off the compressor because pressure is too high. Most of the time, the switch turns on the fan at 17 atm and turns it back off at 12 atm to regulate pressure inside that range.

jim! you da man....thanks for that 411...

nonetheless, works great now...

thanks!
