a/c cooling not working correctly?

I'm going to assume you mean it blows cold from passenger, but not drivers side. Sounds like a left temp door actuator. It should have a code in the ACM(air conditioning module) that will correspond to a repair.

Here is a guide to help you see what I am talking about with the actuator location int eh diagrams below.

Check out the diagrams (Below). Please let us know what you find.

The AC blower motor under the dash started to not work and give me problems. We would hit the dash or close the door and it would start to work again. We were about to replace the motor when a friend who thought he knew what he was doing took the wires going to the motor off and out of the plug. Now we are not sure if the are in the right order and we don't know if he shorted anything out. We are looking for a wiring diagram to aid us in finding the right placement of the wires coming from the resistor box to the motor and to see where else the wires go so we can test everything else before we just replace the motor and it still doesn't work. Also is there another blower motor besides the main one under the dash? We had some problems with the car running rough but with your help and little investigation/ testing we finally fixed the problem in the wiring for the coils. All coils and wires are now brand new and the car runs beautiful. Please help if you can by sending a wiring diagram for the ac system/blower motor and resistor if you can. Also any tips would be great. I believe the resistor is fried as well as the motor but I'm not sure of anything beyond the resistor as I don't know where the wires go to. Thank you!

Please see pic of auxiliary blower motor has two wires both orange and will normally only connect one way. get this scanned for codes as it may be the blower control processor.

I pulled the blower motor control processor and it's burnt inside. I contacted the person who "fixed" it last time and he said the wires sparked. I said yup you made them spark idiot lol. Now where does the sp input come from? The control panel right? Also I'd like to get the rest of this wiring diagram to see where the wires go and other parts on the circuit. Is there any way I can see it? I believe the burnt processor is the reason for everything but I'd like to have it incase.

the blower module if that is what you are talking about goes to the instrument panel module a fuse, blower and ground. it may have more damage to instrument module maybe. if I'm looking at correct one it's $65-95 at rock autoand may need a pro with a scanner to install it.

This guide can help us fix the problem

Please run down this guide and report back.

I should be able to get the wiring diagram at my local library? I'm really hoping it's just the control processor and I don't need someone with a scanner. I have a pocket scanner but that's it lol. I will be installing a new control processor today and I'm hoping it does the trick. If I need any other help I will let y'all know.

Replaced both actuators air was cold for a day....the compressor is clicking on and off and air is blowing hot inside the car

If the compressor is cycling, then there is an issue in the gas system. This video will show you how to fix it.

i can hear the compresor come on but i get no cold air the car has low milage. it just blows hot air what is the main problem these cars have with there ac systems? thanks rich

do you have a light on? like AC low refrigerant in message center? ck your codes its either off and warmer or off and down on the mode button on the heater controls at the same time, with your key in the on position, look in the message center for the codes, write them down and post them here

Warm on driver's side, cold on passenger side, hot in rear. Help!

good morning

there are blend door motors under the dash. it sounds like the drivers side has failed. you can get it at a parts store and replace it yourself.

The compressor will not even kick on. Could it be that all of the freon has leaked out? Please help as soon as possible.....the wife is on me.

My caddy stopped blowing cold last year. A mechanic friend took the relays out in the fuse box under the hood, cleaned the contacts, and put them back in. It then started working. Same problem this spring. I took it to Tuffy's locally and checked pressure and I had 1lb 12oz, so PLENTY of freon. I'm going to go home tonight and screw with the relays to see if I can repeat his magic last year then, if that works, order new relays. I'm also taking it to a shop to have the brakes checked so will have them check the relays and sensors while they're there. I'll post the results. In the meantime, you may want to call your local shop and get a free A/C test. Most places offer a free test.

i cannot get car to blow cold air i checked freon,compressor,belts,fluid.it will bow out very hot air on passanger side an ambient air on driver side an rear air. Never felt cold air since i bought car. Freon compressor are fine. Also no outside temp reading on my digital dash bord its blank. Please help!

what are the exact pressures on the ac system??

Roy

I dont remember it was a cheap tester from advance auto,i do no that it was right next to the red,right next to it,cause i asked if that was a problem!

advanced auto is parts salesman, not techs.

we need the pressure to see what is happening so we can further help you.

Roy

I said i used an advance auto pressure test i felt like that was a cheap test comared to a shop test.an i cant remember exact but the needle was right next to the red but still in the cold but very close to the red! (preasure test)

where do you charge the a/c on 2000 cadillac deville? I know there are two sides, do you charge both, or just one side? thank you

ok, sorry about the advance.

can you hook it back up and give us the high and low side pressures while running?? pressures never are a sign of freon level but it will help us in determining other operations

Roy

Hello,

The two service ports are near each other on the refrigerant line headed from the condenser to the evaporator. Here is a diagram and a couple of guides to help you get the problem fixed.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Ok sorry i was talkin about freon level but i cant till tomorow cause im at work is that ok?

sure, when you can. there is always someone hear to answer.

Roy

Thanks so much i had the pressure checked an it was very low it took 1 &1/2 cans it blows cold but not as cold as i exspected it was profetionally put in an checked so it was filled with freon to the t i now thats important, at one point i thought there air cut off an back on,on the drivers side, also i still hadnt got the ambient air temp sensor yet its on order, any help would b appretieated....

ok, what were the pressures??

Roy

Lol i dont no the tec did all that i remember below 200 an 42 or something like that.

I understand that a loud ratchet or clicking noise comming from dash when air conditioner is on is a popular problem on the Devilles. Does any body actualialy know what is problem. It sounds like when a vent door is operating some gear is slipping.

there is an actuator for the vent doors down by the gas petal, the gears strip out, operate the system and put your hand on it if you can to ck it

268 liquid 48sucktion thats what the tech told me i didnt think it was that exact but thats what he said!

low side is too high. he may have overcharged it or the orfice tube may be clogged with dirt

Roy

Ok low side is sucktion or liquid an can u tell me what it should be?

Also would the ambient temp sensor hinder the air in any way?

I recently experienced a clicking noise under the dashport (driver seat). How difficult is to repair this problem?. The repair shops gave me different astronomic repair estimates. Do you have a manual that will guide me through to resoilve this problem?
Thank you

thats an AC problem? you need to describe it better than that

in most cases, it should be 30-35 lbs. the high side should be 2 times the outside temp plus 15%

Roy

I dont no if u got my second question about the ambient temp sensor?

yes it would but you need to have the system operating correctly first.

Roy

Ok i will check again tomorow an write down cause from what i saw i think he is wrong i now he added freon an it was at 200 an then he added more an it went a little below 200mabey 190 an the other was 43 or 33 an when he added more i did not recheck that but i will write down tomorow thanks an i will b donateing money on the 3rd when i get my check, you are a blessing thanks again.

good luck

Roy
