I have a 2005. Chevy silverado 4.3l and have ac problems I cehecked refridgerent its good actually all they way in red (but I figured its cuz it isn't working) and I have power going to compressor clutch the blower motor still works just blows hot fuses are good and I can spin the clutch on the front ofnthencompressor by hand but it wont spin with ac on its an expensive fix and I don't have money to get it tested and then fixed going through a rough patch with money and I live in Texas so yeah its hot and ac was prologue used a lot before I got the truck it worked. Great then one day just stopped do you think you can help determain the problem. Thanks

Yes I have power to the clutch and its manual climate control but the lights went out on it idk if that matters it all still works if I put to floor it goes to floor and defrost still does it just the illumination lights aren't working anymore. So you know I good places to get AC compressor clutch I also heard if the clutch goes out then there's probably not much life span on the compressor left and since I live in Texas I'm wondering if you think it would be better to get both or if it matters

The way i always decide on to replace the clutch or the whole compressor is by the price difference.I would check http://www.rockauto.com also i copy and paste the part numbers to amazon to see which is cheaper with shipping.

If your tight on money your best bet would be to go with just the clutch for now. Because betime you buy the compressor drier orifice tube charge etc thats a lot in parts alone.

To have to buy a new drier and all the above when I buy a new compressor? And what about a salvage yard for the clutch or would you just suggest getting a new or rebuilt clutch from that site or Amazon I looked online its going for about 180 to 200 hundred just for the clutch

Yes those are things you should change with the ac compressor and have to replace to get a warranty on the new compressor. What size engine do you have?

If you read the part description on rock auto it shows two different parts one for a denso compressor and one for another compressor. See if it says denso on the compressor or something else. Also if you click on the part number at rock auto it will tell you all the vechiles the part fits. So that way if you went to pick apart to find it you would know where to look. It fits a pretty wide range of vechiles.

OK I will check that out and let you know also I have another question my oil gauge is supposed to be at about 60psi I guess I have good compression but the needle sits right under 40 and goes up to 60 when I'm on the gas and my speedometer will just suddenly quit working also I heard maybe the oil sending unit for my oil pressure probably do you have any ideas on the two
