Question about 1990 Honda Accord

Open Question

The air blows out hot. the compressor is fine and it is full of freon...Why does it not blow cold? It was working fine a few months ago. I had a shade tree mechanic work on it and he messed with the relay switch, and change the thermostate in it, now we don't have air.

This is a common problem when the AC system has a low charge.
If this is the case, you have a leak somewhere. Do not try to fix it yourself without the proper equipment.

SOURCE: My A/C stopped working on my 1995 Accord Ex. It'll

On most car aircon systems there is a high pressure switch built into the system. This is a small switch usually with two wires threaded into the metal pipe near the dryer/condenser. This switch is only there incase the pressure gets to great in the system it shuts the compressor off.
Sometimes these can be faulty and turn on and off when the feel like it. They are not that dear about $50.

Easy way to check if thats the problem is to find the switch disconect the plug with the two wires on it start the car and put on the aircon. Using a small piece of wire bridge the two wires in the plug together. If this is the problem you should hear the clutch on the compressor engage every time you touch these wires together. If you can let go of the plug with the wires joined and without it touching on any metal and go check inside the car for cold air.

Hope this helps.
Cheers

Hi there. When a compressor is replaced, two things are in fact being replaced - both the compressor and the refrigerant (Freon) and if the problem is resolved as a result which of those two replaced elements caused the original problem? Well you will never know and so before the compressor is replaced you need to have you’re A/C system recharged – it’s by far the most cost effective initial thing to do. In general A/C systems loose at least 10% of their effectiveness each year through loss of refrigerant and so given the age of your car; it’s the first thing to focus on. A professional A/C centre will also be able to tell you whether your compressor is working properly after having a refrigerant recharge by the monitoring the operating pressures in the A/C system.

If Freon was "added", the system may have moisture in it and that causes blockage of the expansion valveand makes the soamolies hijack oil tankers. Just kidding. Figured this would be all foreign to you anyway, no offence.
Ok, Adding freon is not really a good fix. The system should be evacuated with a vacuum pump to remove any moisture in the system which will freeze and block the expansion valve, Hence, no cooling.Having the signs of this problem already should have called for evacuation. Adding freon from a kit increases the possibility of introducing more moisture into the system. You will need to have it properly service at this point. The drier will also let go of any moistue it has trapped when evacuated for 30 minutes @ 29 in. of vacuum - good luck

SOURCE: blows cold out of left defroster and hot air out of right

There are small doors within the heater/AC components located under the dash that direct the flow of air. Something has gone wrong with the operation of these doors.

I doubt this is a do-it-yourself project. Significant disassembly is required.

1995 Buick Century blowing hot air.


A mechanic would check the system with a set of pressure gauges. If the compressor is running, the low side would read around 30psi and the high side would be around 250psi. That is how you know if the system is full of freon or not.
You may have to get a professional diagnosis to proceed. If you replace the compressor, the accumulator needs to be replaced and a vac pump is used to pull all of the air out before the freon is added.

A/C blowing hot air 2000 CDX Daewoo


over filling it was a big mistake, so was guessing.
the freon is added by weight, from empty. not volume.
if the compressor spins, and no cold air , then its a big problem
the only tiny problem to cause this would be leaves packed in evaporator coil. (deep inside air box in cab)
take it to a shop before you damage the compression and fill the whole
thing full of metal chucks wrecking everything, at once $$$$
do not let the compressor run, if it dont get cold. do not.
get it serviced.

My lincoln mark lt pickup won't blow cool air


My lincoln had the same issue, first it was the A/C compressor (original). I replaced it with another one (used) and worked for 1 month. Then back to hot air. "A/C experts" told me the compressor was out again. I took it to a Mexican auto shop, old building where the guy works alone and to my surprise...HE FOUND THE PROBLEM!! There was no freon leaks, the lines were freezing cold inside the motor, checked freon>>full. He then checked the filter. This filter is on the end of the line where it is crimped that allows the freon to flow thru. Im no mechanic so explaining what it is, forgive me. I can only show you...the line is silver ad in front of you by the radiator, and its the same tube that goes to where you plug it to add freon. There is a filter that was clogged up and prevented the freon from flowing. He removed all the freon, vacuumed out the system/line, and replaced the filter for less that $3.00. Added freon and his cost was $80.00. Thank God for honest people who work hard for a living. I buy the parts, he replaces and I continue to give him my business. Other expensive auto shops with fancy buildings/prices My Lincoln Mark LT now blows arctic cold air!!!

A/C is blowing hot air. Freon is full, compressor


Not sure how you know if the freon is full without the unit running. There are a number of switches which can keep your A/C from coming on. There is a low pressure switch which is usually located on the larger line and sometimes located on a silver cannister (called an accumulator) which is the low side of a compressor circuit. There is also a high pressure cutout which is usually located on the back of the compressor unit. Both of these switches can be jumpered out to see if they are the reason for the compressor not working. You remove the two wire connector to either switch and place a small jumper wire between the two wires on the connector block. The other reason my be a low idle cutout switch and this will also usually be located near on on the compressor. You can also test it the same way as the other switches. If it is the low pressure switch then of course you will need to add freon which you can purchase from any auto parts store. They usually come with instructions and all the equipment needed to add in freon. If it is high pressure, then some of the freon should be recovered from the system by a technician. If is the low idle cutout then you will have to take it to a mechanic to understand why it is idling so low. Hope this helps.

2003 Tiburon air conditioner won't blow cold air


Most likely your problem is the same as mine, which means you have a crack in your air compressor therefore no matter how full you fill the freon it will always drain (or blow) right out. Solution - get a new air compressor. Try to find one in a chop shop junk yard type place if you can do it yourself.

Alternate problem - freon can lose its charge. You can take it to just about any auto store and get the freon charged up for about $70. If that doesn't fix the problem it is likely the compressor.

A/c blowing hot air. 3 out of 5 vents are blowing.


With regards to you a/c not blowing cold there are several faults that could cause this. Your compressor may not be working, they may be a restriction in your A/C lines, your compressor and/or evaporator may be clogged, you may have a leak, or i could be something as simple as fuse.

Sounds like there is either

1. Too much freon in there

or

2. Not enough freon in there.

Freon (R) being freon or low CFC equivalent.

Sounds like the system is working fine, then the condensor or compressor gets too cold and freezes up (or gets WAY too hot). when you turn the A/C off, the system has time to stabilize and return to a more 'normal' condition.

2001 S60 Air blowing hot


There may be a problem with the AC compressor pressure cycling switch, it turns the AC compressor on and off as required to maintain proper pressure in the system, it is located in the low side line (large AC line) under the hood, it will have 2 or 3 wires going to it.
