Refrigerant does costs a fortune, and you can chalk that up to previous versions that destroyed the ozone layer. 

 The new ones are still bad as greenhouse gases (some are crazy bad!!) but they no longer destroy the ozone layer. It is illegal to vent any refrigerant into the air. It is supposed to be recovered using a recovery machine if possible. If it all leaked out, then there's nothing that can be done about that except finding and repairing the leak(s), pressurize with nitrogen to test for pressure holding, then evacuate the system with a hard vacuum, and recharge to a specified weight. 

 If you ever have to do the work yourself, the biggest danger is the refrigerant is always under high pressure. Even when it's not running, it has a very high pressure. It will rapidly expand when released into the atmosphere, and will burn (FROSTBITE!!) skin on  contact. Dangerous.

 Get someone trained to do it, or read like crazy until you know what you're getting into before tackling an A/C repair on your own.

hang with me guys.  I just came back, i dont believe the compressor clutch is engaging.  in fact i didnt even hear the compressor cycling this time.  so i guess get the relay which i can get, but not exactly sure which one in the box it is.  it doesn't specifically id clutch relay.  there is one that says i  "ac compressor relay" which also includes day time running lights, AIR system, and rear window defogger.  theres also another that says "ac relay".  hogone

Does the compressor clutch actually engage? Yes, then no refrigerant left in the system. NO, then the A/C clutch fuse and relay should be checked for correct operation.

A leak test can be performed using dye.  The use of an electronic refrigerant sniffer is very difficult in an automobile.

Proper vacuum evacuation of the system is critical and it should be blown out a few times with dry nitrogen before pulling the final vacuum and charging.

Good luck.

I shouldn't say this but my '94 F-150 with 310K miles still has A/C that works, never had to add any R-12 to it . . . .yet.  I do have some sitting in the garage, just in case.  Have had 1 clutch job at 260 K miles, so that shouldn't be a problem for quite some time.  My only worry are when will the next deer jump in front of me (that would be # 32 kills).]]> Mon, 26 Jun 2017 20:16:43 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95591#95591 SILVERADO AC : Hogone, Yeah it's low on... https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95580#95580 Author: mcarter

Hogone,

Yeah it's low on Freon. 4 years is awhile, sounds great you have a log. All your symptoms are low pressure. What they do is start and stop. Near the accumulator is the switch, you can jumper it, but with low Freon you may or may not get cold AC. It can't run on low pressure. If I could look at it I could help. Sounds like a sweet deal. The low pressure switch is a two prong switch with a plug on it (a connector), it won't let the compressor come on with low pressure. I checked YouTube and they have some informative vids. A good AC dude will figure out in 5 mins, I could.]]> Mon, 26 Jun 2017 19:00:12 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95580#95580 SILVERADO AC : mcarter: thanks, heres more info.... https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95577#95577 Author: hogone

mcarter:  thanks, heres more info.  has 121,000 miles only, it was babied. engine is clean and spotless. ill look at hoses/belts again but they looked pretty normal and some have been replaced for general maintenance.  one thing Ive never had to messed with is ac, so pretty green here.  know basic repair and i do alot myself. when we pulled up hood, compressor would come on for about 10 seconds, then off for say 5 then 10 ect. His log says freon put in 4 years ago.   not sure if that is useful info.  where is that pressure switch?  hogone

Hey Hogone,

I am a big fan of Silverado's, just sold a 93 that had 340K on it. The fact that it has been sitting a year, makes me think it has a slow Freon leak. Hoses and belts should be checked and replaced as appropriate. Take it to a certified AC repair center. They do not have to fill with Freon, they can pressure check AC with nitrogen. Big price difference. If it was me I would bypass pressure switch and see if compressor runs. If it does the Freon is low. Once pressurized they can check for leaks. Once leaks are fixed, they can fill with Freon. Relatively simple repair. Belts don't cause loss of Freon, hoses can but are easily detected. If compressor is bad, it won't ever come on. Just pick a good place to take it.]]> Mon, 26 Jun 2017 16:27:10 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95551#95551 SILVERADO AC : All rubber components degrade... https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95543#95543 Author: GlueGuy

All rubber components degrade over time regardless of the gentleness of usage. Even if the miles are low on the tires, they will still degrade. For a primer on tire date codes look here: http://articles.extension.org/pages/73045/tire-safety:-expiration-dates

Likewise, all the hoses (water and AC) generally have an expected 6-year lifetime. A 1999 vehicle is 12 years past all the original equipment dates, and 6 years past the second replacement date of 2011.

this vehicle was very well taken care of, it actually lived right across the street from me and I've known it since he bought it. tires are like brand new. very good thorough maintenance log; actually not really that much done except oil changes every 3500-4000 miles, and a few minor repairs. it was his pride and joy but he no longer is able to drive. just concerned about ac. obviously it can be fixed, but what it is and how much is the concern. hogone   ]]> Mon, 26 Jun 2017 15:26:03 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95539#95539 SILVERADO AC : That vehicle is 18 years old.... https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95525#95525 Author: GlueGuy

That vehicle is 18 years old. All the AC hoses and seals would need to be looked at (and probably replaced). Plus the refrigerant is probably gone. 

Good time to look over all the rubber under the hood, not to mention the rubber on the road. Check the expiration date(s) on the tires.

my son is looking at a 1999 chevy silverado. its in pretty good shape, hasn't really been driven over the past year. always garaged and kept up well. the only thing we found wrong was the ac does not work, or I should say blows warm air. could be a wide range of things from basic freon to who knows, compressor maybe. obviously I know I need to bring it in somewhere, but just checking if anyone ever had similar problems with a similar truck that could maybe give me some leads. thanks for any info. hogone]]> Mon, 26 Jun 2017 07:39:23 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=10235&PID=95518#95518
