AC problems again

I have a 2001 Dodge Intrepid SE 2.7 V-6. I recently charged my AC and after a few problems, the AC blew cold for a few weeks up to today, Today I turned the AC on, it worked fine, when I got to to a stop light I turned it off, a few minutes later, turned it back on, nothing happened. Check the AC compressor, getting no pressure when car is on, but when it's off I get a static pressure reading, the clutch is engaging, I made sure of it, after checking all the fuses and relays, the clutch is engaging, but the compressor I'm not sure if its running. It did this to my last time, I couldn't get a running pressure measure, but I could get static pressure readings, what should be my next move be? I don't want to try charge it, it won't do any good until I know if the compressor is seized or not, could the drive belt be causing any problems?

When you look from the front of the car into the compressor clutch, the center part is actually rigidly attached to the compressor shaft. When the clutch is not engaged, the outer (pulley) part of the clutch will be spinning when the engine is running, but that center part (think: compressor shaft) will be at a standstill. When the clutch is engaged, if the center part is rotating *with* the pulley part, then the clutch is by definition running.

Recognizing that so you can determine if the compressor is being turned is the first step.

thank you. I checked the pulley and the clutch, the clutch is attached to pulley, right? Its all spinning, I noticed that the center part won't spin when the ac is not on, which is normal

I checked the clutch, and it spins when the ac is on, and doesn't spin when the ac isn't

What are you using to get the pressure readings? A proper AC gauge set or relying on the cheap gauge of one of those DIY cans of refrigerant you buy at the auto parts store?

the cheap gauge, I get a high static pressure reading from low side, Without doing too much more, I'm going to Meineke tomorrow after school to get a diagnosis. Their website says they do it for free, so hopefully they can tell me for sure what is wrong, and how much it's going to cost.

If you have a Harbor Freight store near you I'd recommend getting this gauge set:

http://www.harborfreight.com/automot...set-92649.html

It's currently on sale for $39.99. You really need something like this to accurately diagnose the AC system. You need to know what the High and Low side pressures are.

If you're unfamiliar with AC service..I'd recommend getting a shop to look at it.

Just be careful. I don't have any personal experience with Meineke, but a lot of these chain stores are experts at "upselling" if you know what I mean. Think thru everything they tell you it needs, and check back here on anything you don't understand so you don't get taken.

Ooh! That's a deal and a half.

I agree. That $99 brake job becomes $600+! If it's a "free" evaluation go for it. Then when they start piling on things you "need"..come back here and let us know. Also if they claim that you need something...like a compressor for instance...have them give you details and how they determined you need that part.

Thank you guys so much. Yeah I'll be on my toes, Meineke screwed over my brother once when he had the brakes checked, they checked them, and told him that he couldn't leave until they fixed the brakes for it was a safety hazard ,700 bucks later....

I'll make sure they break everything down to me and check with you guys, and with other people that I know that know more about cars than I do. But yeah, their website said they diagnose for free.

I took it to them today, they didn't even look at it, they ask me a few questions, such as if I topped it off, I told them I did but the charge went out after two weeks. Without even further diagnosing it by inspection they flat out said it was a leak before even looking at or testing the system, what a bunch of bunk. So that means I have to plunk down 100's of dollars just to have it checked? A place said they did AC service for 29.95, which I'm sure is before the cost of refrigerant, but that's only if they are able to charge it, I'm not sure if they would actually do the dye test or any of the other tests that would indicate the actual problem of the non-existent AC, thats probably the fee for topping off without vacuuming the old stuff out and putting clean stuff in, I can top it off myself, and that's not a solution right now, whaddya guys think? should I take it to the shop thats gonna charge me 29.95 plus the cost of refrigerant?

also, when I do the psi check on the low side when the compressor is on, and it says 0psi, the gauge goes below 0 like its sucking, is that just the suction port or the compressor? is it possible UI could have got moisture or air enough in the system to cause blockage? thank you guys again.

If you don't know what you're doing...I suggest you take it to a professional or shop experienced with AC systems. Hate to see you get injured or damage the AC system by playing around with it.

who should I take it to? Do you happen to know, roughly, what a pro would charge just to check? thank you. Like I said, I really am not trying to mess with it myself anymore, I want to take it to someone, but alot of those places are rip-offs, should I take it to the shop that charges 29.95 for ac service, or do you think they would actually help me? thank you

I don't have a clue. All I can suggest is you call around to different places and ask what they charge for the diagnostics service. As you already found out don't tell them you've been messing with it...just say it stopped working. If they don't put a proper gauge set on it..there's no way they can diagnose anything. You might look into some places like Firestone or Goodyear, etc. Meineke and some others have been known to lure you in cheap and then talk about several hundred dollars for repairs that may not really be needed.
