Good afternoon all. RR Full Size SC 06 with 70K miles. *BackStory* Most recently the A/C stopped working and it being 93 F I'd like to get it fixed. So I took it to get looked at and was told by 2 different shops that it may be a problem with the Expansion Valve sticking open. Apparently they filled it with freon and the A/C Compressor was turning on but no cold air was coming out. So I was quoted this.

Try not to laugh. But I was told after they do the service if it still didn't work it would cost an extra $1,000 for A/C Compressor.

As expected.. I am finding the parts online for half than what they quoted and I figure if I want to keep old Rangie I'll have to get familiar with some dirty work.

I was wondering and looking for some solid advice with A/C components as I have no experience in it. The process looks a little hard but do-able in the Rave. I believe this here (The Expansion Valve) is what is needed to be replaced. But do I have to drain the system first? If I remove the Valve will damage occur? Any easy way to go about doing this process? I was told the condenser should be replaced to on the ticket.

I would hate to put it back together and have it fail again so I am debating that I should replace the drier. Any tips or insight into my A/C Problem? What should I replace and what should I leave in? Any ways to do this easier? I'm asking in advance because before ordering the parts i want to get them all at once and not have to mess around. Thank you all.

Hi there milleR...! If it helps at all, I'll let you know that I have very similar situation as you...same RR 06 SC with 77K miles.... compressor turning but no cold air... however, the shop (air conditioning specialist for all cars, only shop that can fill by weigh and not with just pressure gauges) determined it was the compressor itself! There is always a bit of a guess, but as my air was not really very cold when recharging, the thought is that the pistons are leaking pressure from wear...
In general, when there is a failure, several parts are replaced to avoid "contamination" . Example: you change the compressor, but metal particles in the remaining system will enter the new compressor and ruin it... !
So in my case, to e sure, I replace also the condenser (with incorporated filter/drier) and the expansion valve. They told me that the evaporator, although being the most physically delicate part in the system , is in the "low pressure" area and would not be dangerous and need changing....Someone here could confirm/deny this....
So it's a question of feeling "safe" and spending more for parts, or risking it and only buying only the necessary.
I just have the added problem of living in Venezuela and have to wait a month for parts to arrive by ship...
Maybe somebody here can diagnose with more certainty your problem and advise you better! Best of luck !

Thank you very much! I will keep the info in mind. I'm planning to just replace it all since i'll be in the engine bay re-doing most everything A/C.

It'll be about $544 down but its alot better than $2,500 and after reading the horror stories on here of people who let shops work on them i'll have some peace of mind. A question btw for the A/C Compressor. I read that there was a mix up between which ones are compatible for the 06 L322. I'm thinking about just biting the bullet and going with an A/C Kit as listed here. Anyone see anything sketchy?

http://www.buyautoparts.com/buynow/2006/Land-Rover/Range_Rover/A-C_Compressor_and_Components_Kit/60-82376_R6

It includes

- New Compressor
- Oil for the Compressor
- O rings
- Condenser (W drier)

Is this the go to for all things AC kit I need or should I save my money and buy elsewhere? Thank you in advance.

I just went through this on my '07 SC.

Go with OEM Hella Components. Don't buy from the dealer. I purchased from Rock Auto. Hella/Behr Compressor: $505. Hella/Behr Condenser: $239. Hella/Behr are the original components for our rovers. For the expansion valve you can get it from BMW for less than the price from land rover as it's a BMW part. Don't go aftermarket for the expansion valve. I did and it was humming very loud while driving. I had to discharge the refrigerant then buy the OE part from BMW dealer, re-install and re-charge.

I followed many recommendations and bought the original Sanden. If you shop around you'll find at similar price. For the rest Behr is quality!
