  • pedrocardozo May 25, 2009

    Yes, the blower is working fine. If is the dash switch,how will i check it?

  • pedrocardozo May 25, 2009

    Thanks, I will be waiting for an answer!

  • pedrocardozo May 25, 2009

    yes, it is OK!

  • pedrocardozo May 25, 2009

    yes,I can. If I wired it directly to the battery, it will run fine.( By-passing the Plug,of course!)

  • pedrocardozo May 25, 2009

    ok, will try that. TOMORROW WILL post the results.Thanks for ur help, may GOD bless you!

  • pedrocardozo May 27, 2009

    Well, it turn out to be out of freon!!!!!!!! It must be leaking from the compressor itself, because i do not see any oil spots!

    Good question. You'll have to take your dash apart, and see if there is power coming through the switch to the ac. Tell you what, i'll check one out, and get back to you tomorrow, if that'll work.

    Maybe it's your switch ... the dash one. Your blower fan is working good?

    Is it charged fully? You won't get power there unless the low pressure switch allows it.

I never asked you the simple question. Did you check the fuse? It should be #14. 30 amp.

    Okay. can you turn the compressor clutch by hand?

    Well, it's gotta be the switch. That's all thats left. I think the switch/ ac relay is all the same thing, but ask your parts guy. There are 2 fuses that relate to the ac, but the other one, #4 is hooked to your fuel sender etc. so it can't be that. If yopu have a decent auto wrecker close by, i think i'd go grab a switch, or get a new one.

My ac quit working don't think compressor engaging all fuses good


Check the wireing on the front and back of compressor! could be grounding out wrong and or loose conections. My 89 buick had some of the same problem and I had to rewire all conections to the compressor! if that dosent solve the problem then you may have a faulty clutch!

Can i use a smaller serpentine belt if i bypass the air conditioning unit?


In some cases this can be done-but you do not mention the engine you have-also, there are bypass pullleys that some sellers have for just such circumstances, google bypass pulleys for your engine-you sometimes can do this yourself if you keep in mind the rotation of all pulleys has to remain the same,

Engine speed decrease when start the AC


That's normal. When you have a 4 cylinder, this can be expected. Most people just turn the ac off when they want to pass someone. The ac compressor just puts a load on the engine in low power/torque apllications like a kia 4 cylinder.

Air conditioning not working on dodge intrepid. added freon. still blowing out HOT AIR. what do i do now?


I have 2 ideas.

Idea 1: The clutch in your ac compressor could be out.

Idea 2: The ac compressor isn't getting any power. Use test lights on the connectors to the ac compressor to make sure it is getting power. (Test this before trying to change the ac compressor. It is way cheaper to fix a connection than to change the compressor.)

NOTE: ac compressor clutch is not available seperately for this car at discount auto parts stores.

AC compressor will not energize


First thing you should check is all your grounds, on the body and your battery connections. Also double checked to make sure you have the air conditioning on with the fan on. If this is good the next thing to do is to get a wiring diagram. Verify that there's power going into the switching and coming out of the switch. Next find the compressor relay verify that there's power going two it. If this is good use your tests light to ground out the relay. If this works find out where the ground wire goes to the computer or the wide open relay. Good luck.

I cannot get the compressor to come on. We just put a new one in.


Did you make sure to fill the AC system to the correct pressure recommened by the manufacturer? If not, the AC compressor switch will not be activated and as a fail safe it won't allow the compressor to come on at all. This is to keep the compressor from running when the pressure in the lines is too low and potentially damaging to the compressor (not enough lubircation). Double check your numbers, if this doens't work, then check all your electrical conections and the AC relay and fuses.

Adding freon to the auto air conditioner, the


On that model,it will cycle on and off while you add freon.If it does not ,then the ac system might have a problem.The low side pressure switch is located on,or near the accumulator .Unplug the switch and take the wire end plug and connect the two plug in`s together(cross it out on the wire).This will make the ac compressor engage and you can charge the system,do not leave the wire connected,plug it back up to switch.If the ac compressor does not come on ,then have the system checked out.

My problem is with the AC on my 91 Civic Wagon. It suddenly became inop after an engine change. Wiring seems to be good along with relays. My problem is there is no ground on the clutch relay to actuate...


changing or swapping engine should have no effect on ac unit if you have everything plug back in correctly. I replace my engine also and plug everything back in with no problems. when you press the ac button does it light up? if not than you have no power to the switch and to clutch/compressor. take a meter tester to see if any power going to the compressor when the ac button is on position and also to the ac button. if not check your relay see if its good and test the plug where the relay plug in to see if any current flow though it. I suggest to pick up Chilton manual repair book from auto zone or pep boys for schematic.
