Air Conditioner Problems

My air conditioner stopped working about 10 months ago at the end of the summer. I didn't think about recharging it because winter was about to hit. Since summer is approaching, I thought Id go ahead and recharge the conditioner myself with the proper coolant my manual said. I bought a can with the gauge so I could better know what is going on since it is my first time. (I am not a car gal, I am a premed student) So I had my neighbor (car guy) put the entire can in while I had the vehicle on running full blast on cold with the A/C button on. As we filled it, still no cold air. Then he noticed that my compressor was not clicking in. We checked all the wires and have yet to check the fuses (which I am uncertain which fuse to look for). The car has 100k on it just as of last month (April) and the coolant we bought is supposed to fix leak but how is it supposed to fix them if the compressor isn't turning on. I did reset the battery thinking it was a computer error but still no fix. Please help, thanks!

You may have had an electrical problem all along and now you've added Freon on top of a full charge which isn't good. put the gauges on both the high and low side. and see if you are charged or low or overcharged. the compressor can go out on high pressure or go out on low pressure. I am not sure which you have. thwere are relays that come into play when the charge is high enough to satisfy the low pressure switch. the relay is in the power distribution box under the hood. there is also a fuse under dash for the ac

SOURCE: Air conditioner

Is the fan running with A/C on at idle? If yes try blowing out the radiator and condenser with compressed air.

SOURCE: air conditioner, fuel gauge, and temp gauge all stopped working at the same time

Three possibilities;
All related to blown fuses,

1- Fuse blown in the engine compartment LH.
2- Fuse blown in the cabin forward LH below the dashboard (below your legs left hand).
3- Fuse blown in the harness (wire bundles) below the dashboard very easy to reach with your hands “just look underneath steering wheel ".

U said " The air conditioner blows, but the air is not cold.
" Yes only the fan working which might receiving power independent all from those other mentioned things.
If all fuses OK. Then look for broken wires.

No, these problems are not related. The radiator is a sealed system and you may have a leaking hose, bad water pump or the radiator may have developed another hole in it.

The A.C problem is one of three things.

1. The A/C Freon has run out of the lines. This is a fluid used to maintain cold temperatures and produce the cold that actually comes out from your vents. It could be as easy as recharging the A/C system.

2. It could be the high pressure line that feeds the freon to the system. This would require replacing the hose and recharging the system.

3. It could be the A/C Compressor is bad and need to be replaced and the system recharged.

Each of these are progressively more expensive and should be fairly easily diagnosed, albeit by a automotive professional. I would not suggest you try to fix this yourself.

I'm betting it has something to do with the shift lock actuator or the harness to the actuator. I'm pretty sure it is located on the top of the steering column on your vehicle. The lower part of the dash will need to be removed and then the steering column lowered in order to gain access to it.

This vehicle does have an airbag and unless you experience with airbag systems I would not recommend tackling this yourself.

unplug the interlock. Replace the fuse. Start the vehicle. with your foot on the brake manually release the interlock with you hand and shift through the gears. If the fuse does not blow your on the right track. If the fuse does blow let me know and I'll get you some more info.

Let me know if you have any questions and thank you for using

My AC worked great until last year and then after a power steering hose leak was discovered, the ac until stopped blowing cold air. I took it and paid 75.00 to have it recharged with coolant and it worked...

My air conditioner started blowing hot air last summer. I put coolant in it and didn't run it until the beginning of summer this year (2011). All of a sudden it started working again. Sometimes it blows hot but if I keep it running full blast the coolness comes back. I don't know why this happened.

Love mine too. I had the same prob with the a/c...found a fix online where you take the switch panel out, take it apart, clean the contacts with alcohol and then write on them with a #2 pencil (coat them with the lead) and then reassemble and it worked like a charm for me. Mine started to do it again this year, but it at the end of summer and I didn't get around to doing it again, but will before I need the a/c again. And time again for front brakes and rotors for me! 85k and going strong!

Do I need to add coolant to the air conditioner?

You don't need to add refrigerant unless it is cycling on and off quickly or isn't getting very cool, you don't want to over charge it.
