Question about 1990 Toyota Celica

1 Answer

Hi..I have 90 Celica GT model and I came to Autozone to pickup can of Freon to recharge my ac.. Autozone guy came out to check make sure compressor was working when I push the AC button. It was working fine before I purchased the freon..And then when I came out It is not working when I press AC button and compressor will not engage anymore.. I checked AC relays but they are fine and he said it may be the cut off switch on compressor..but I am not sure really whats going on...At the time outside temp was 104F degrees and was really hot. Please help I need solutions.

Did you put freon in the car? If you did, and you have too much, there is a "high-pressure" cut off switch, and there is also a "low-pressure" cut off switch. So, if the freon is too little or too much, the AC is prevented from engaging. The best thing to do is take it to a guy who has freon pressure gauges; this is the only way to tell if the charge is correct or not.

My ac blow hot do not hear compressor turn on 90 Toyota gt


It is very easy to check an a/c compressor clutch. Looking at the compressor, you should find a wire running from the pump the wiring harness. There should be a connector where you can disconnect the wire from the main loom, disconnect it and connect a length of electrical wire to the wire going to the pump. Connect the other end to the battery positive and you should hear the clutch clicking in. If you don't, the clutch is bad.
If it does click in, you should look at the fuses (should actually look there first) and the relay if it has one. By the way, if you connect the wire as described and you hear the click, you could actually leave the wire in place and start the engine and you should feel the cold air.

How to recharge the ac on a 99 chevy blazer


Hi Kelea, I'm glad to help!
I see all the time people overcharging there A/C system because someone told them they need Freon, when in fact it turn out to be some other problem all together. But if your sure you need Freon then go to Autozone and buy a bottle of Freon the hose come on the bottle to hook up to the car. I'm sure if you buy the bottle from them they will help you fill the system. However if you live in the St Louis Mo area give me a call. 314-374-5218 Allen. Hope this helps and have an awesome day Kelea.

Problem with ac blowing hot air on a 2002 ford mustang gt


Low or no freon. Bad compressor. If its low, find the leak, repair, evacuate and recharge with oil and freon. CLEAN Freon. NOT a quick fill with sealant. That will do damage the system.

You can jump the compressor without having the key on. Run a jumper wire from the positive post of the battery to the single wire plug for the clutch. If it clicks, find an AC shop and have it checked for leaks and repair.

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!!!

I have freon, and there are no leaks and had a air compressor put in 2 years ago but my car is blowing hot air only


There are a few things that can cause this. First off, make sure that the compressor is turning on when you turn on the AC switch. With the AC on full blast, look at the engine, locate the compressor and make sure that the center hub (the clutch) is spinning, not just the pulley around it that the belt rides on.

If the clutch is not spinning, or if it cycles on and off repeatedly, then your AC compressor is not functioning properly. This could be due to a failed compressor or to a low level of freon in the system.

If the clutch is spinning, then the next thing you should check is your freon level, get a temperature-dependent basic freon gauge, (like the one I posted in the link at the bottom) hook it up, set the outside air temperature on the gauge and then it will show you the ideal freon pressure level. What most people do not know is that having too much freon in a system will cause it to blow just as warm as an under-filled system. The freon level has to be in the "sweet spot" for it to properly work.

If your freon is at the proper level and your AC clutch is on and functioning then it could possibly be the AC switch in your instrument panel, or one of a couple of different parts in the engine compartment, but 90 percent of the time the problem will be found within the bounds of what I just listed. Good luck!

How do i know if the ac needs to be recharged or replaced in my 1990 toyota celica gts.blows hot air.


Normally, if when you turn on your AC the compressor will activate and you can visually see the pump turning if you look. If it turns, then you can attempt a recharge. If it doesn't turn, then first check the fuse for the AC and if that is good then your compressor might not be any good.

While this is just a quick check, and you system will probably take further diagnosis, it is a general guideline that should get you into the ballpark.

Hi I bought a used volve about 6 months ago. Lately when I use the ac the far left vent blows out warm air and it also is not blowing out as cold of air as it used to. I was going to add some more freon...


> I was going to add some more freon and the gauge that came with the can does not fit the valve. There are normally two valves on the AC lines; one is the low-pressure valve (inlet to the compressor), the other is a high pressure line leaving the compressor and going into the exchanger. The low pressure valve is the point at which Freon is added and pressure is measured with a single valve. The high pressure valve is customarily used only by service personal to determine compressor performance and should never be used to recharge the system; they are intentionally different to avoid rupturing the the Freon container. Trace all of the lines to be sure if you have found the right one to use for recharging and measuring the 'low' pressure side.

1996 toyota celica ac not blowing cold. freon is fully charged & ac compressor cluch is on but just warm air comes out the vents


The flap that directs cold air and warm air may be stuck in warm air position. This flap is controlled by a vacuum operated actuator that is attached to the vacuum lines and the control panel. This can go bad. Otherwise check in compressor sight glass to make sure there is no air bubbles or fog, that would indicate a leak in the system
