Hi, you are looking for a 1/2 " aluminum tube (or painted black), when you find that, follow the tube until you find an attatched, rounded cylinder/tanks with wires attatched, when you find that, look for a blue plastic cap, if cap is present, that is your connector! if no cap present , the connector is approx. 1/2" wide, 1-1 1/2" inches tall and attatched to afor mentioned tube near tank/cylinder (actualy called receiver/drier)....good luck, marty

I got a 2003 f150 that just blow hot air when i turn the ac


First thing is to check and see if there is a belt in tact on your compressor and then see whether or not the compressor clutch engages (clutch is on front of compressor in front of belt.) If so and no cold air, u may need to charge it with 134a refrigerant or have a leak that you'll probably want a shop to repair. Good luck and hope you stay cool.

MY AC ON 2003 FORD MUSTANG BLOWS HOT AIR AND DONOT HAVE OWNER MANUEL TO SEE IF FUSE BLOWN


The most common cause for an AC blowing hot air is the system is low on refrigerant. A small leak will eventually lose refrigerant until the compressor eventually will shut down. Most compressors require a minimum of 20psi to engage and chill the air. Most certified service stations can diagnose and recharge most systems for $100-150 depending on where the leak is. There are do it yourself kits available at most auto parts stores that come complete with leak detector (R-134A with dye to show where leaks are) compressor oil, and a recharge hose.

A.c in my 1999 alero is blowing hot air i think it need to be recharged?


FIRST CHECK USING AC GAUGE SET TO SEE IF YOU STILL HAVE REFRIGERANT IN THE SYSTEM. BECAUSE YOUR AC COMPRESSOR FUSE OR RELAY IS BAD ALSO AC HEATER CONTROL SWITCH FAULTY.YOU DONT WANT TO ADD TOO MUCH REFRIGERANT IN THE SYSTEM. WHEN YOU CHECK AC REFRIGERANT THE LOW SIDE PRESSURE SHOULD BE 32 - 40 AND HIGH SIDE PRESSURE SHOULD BE 150 - 228 PSI. WORK SAFELY WEAR SAFETY GOGGLE WHEN WORKING ON ANY KIND AC REFRIGERANT SYSTEM. REFRIGERANT CAN CAUSE BLINDNESS IF GET IN EYES. DONT INHALE R 134A REFRIGERANT CAN CAUSE UNCONSIOUS AND DEATH WORK IN WELL AIR VENTILLATION AREA.

1999 gmc Jimmy only Blows hot air. Diverter actuator is moving and working. Even when compressor starts all pipes are hot. Check 134A and was low. When put in less than a can the compressor would cycle on...


When recharging the ac you need to recover the old refridgerent. That means you have to take out all the old 134 and replace with new 134. On the engine sticker under the hood should tell you how many pounds of 134 it takes. When put in the 134 make sure your ac is on high.

The air conditioner blows hot air. Is there a way I can test for a leak in the system or does this require a technician? I am thinking it's not a compressor because it is blowing.


Apart from doing a low side pressure check, you can try to recharge the system yourself with a refill kit that's readily available at most auto parts stores. If you're concerned about a leak, also get a can of R-134A with the UV dye that will show any leaking components.
RECHARGING AC SYSTEM


  1. Turn the truck on and turn AC on HIGH
  2. Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
  3. Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
  4. Insert the other end of the refill hose to the low side valve
  5. Puncture the R-134A can with the screw on the refill hose
  6. You should feel the system suction the refrigerant out of the can
  7. Check for frost on the AC lines and the air blowing inside the truck
  8. If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

My 99 dodge durango's a/c is blowing out hot air, put in coolant didn't work, put in freon it seemed like it was getting a little cooler but still warm, turned air off next day it was back to hot air...


Most likely cause is a leak in the AC system. Adding refrigerant alone won't cure your problem. Get a can of R-134A with leak detector in it. It has a UV dye that will glow wherever the system is leaking. Best of luck.

A/c blows hot


Your car is low on refrigerant.
  1. Your system requires R-134A refrigerant which is available at most auto parts stores.
  2. You will also need a hose to connect the refrigerant to the AC system.
  3. You will need to locate the low side AC fitting (looks like a nipple)
  4. With the car running and the AC turned on high, attach the hose to the AC fitting,
  5. attach a can of refrigerant to the other end of the hose.
  6. Turn the screw on the hose to puncture the top of the refrigerant.
  7. Move the can back and forth until the refrigerant is empty.
  8. Detach the hose from the AC system.
Check to see if frost forms on the AC lines under the hood and cool air blowing from the vents inside. If the air isn't cold enough, add another can of refrigerant.
CAUTION: Do not overfill the system. If the system doesn't "**** in" the refrigerant, the compressor needs resetting (disconnect battery 5 min in GM cars and trucks)
I hope this solves your AC issue. All the best!

01 mustang convertable i changed the ac compressor now what?


need to evacuate the system check the orifice tube put back together and re-vacuum system to remove the air from the system.
it's cycling to fast which means air in the system.

any air left in the system will counter any refrigerant in the system.

AC STOPPED BLOWING COLD; ONLY BLOWS ON MAX MANUAL SETTING


Your AC is low on refrigerant; The AC compressor needs a minimum amount of regrigerant to run. If and when it does run (while low on refrigerant) the air coming out of the vents will not be cold. The refrigerant you require is R-134A and is available over the counter but if you are the least bit unsure as to how to add refrigerant, taking it to a garage that does AC recharging would be your best play. If you want to try to add refrigerant on your own you will need the following, 1LB can of R-134A, an AC hose adapter to deliver the refrigerant, and preferably an AC pressure guage to ensure you are not overfilling the AC line which will damage the system.
