That's because you don't understand A/C repairs and how they have to be done. When you have a compressor failure, all the torn up metal particles from the compressor spread throughout the system and if not resolved, they will ruin the new compressor with the extreme high pressures. Now you have had 3 compressors grenade into your system. You also have to balance the oil when this is done. At this point you will at the very least have to replace the condenser, dryer and expansion valve but you will also have to find out what made the first compressor fail. Contrary to popular belief, A/C repairs are not for the DIYer.

2003 Toyota Camry mileage: 89,000. The air conditioning was working okay. But, now when I turn it on, the air conditioning knob lights up for about three to four seconds and then starts flashing. Now the compressor will not work.

There is obviously a problem in your air conditioning system. Scanning the computer that controls that system will reveal a fault code that should pin-point your problem.

The A/C compressor on my '03 model Toyota Camry LE does not stay on long enough to cool the interior of the car except when I'm driving fast on the interstate. When I'm stationary it keeps going on and off in intervals of less than a couple of minutes. I stay in the tropics and I have the thermostat set to the minimum temperature.

The system has numerous safety features that could be kicking in because it has a problem. You need to get it checked using a professional set of gauges to determine the reason it is doing that.

Many thanks Wrenchtech. Any ideas as to what the possible problems might be because I do not have access to professionals where I am currently located.

You don't have any choice. Until you analyze the pressures, there is no clue what is happening or why. You can do serious damage to the system if you continue to use it that way too.

Recently the air conditioning system in my Camry was operationing poorly. I added 27 oz's of Refrigerant and it blows extremely cold 38 degrees. I noticed that the blowers where not functioning to capacity. I removed the manual vents form the dash and I noticed inside the tunnels a wire screen. With my air compressor I blew out all four tunnels and three of the four are now operating to capacity. However, the drivers side the air flow appears to be blocked and fucntioning poorly. Any suggestions? Thank you Mike Karavolas.

Remember, what ever you blew through the screen is still in the system. The only thing you can do is remove the ductwork to that vent and check it for obstruction.

I used a paper clip to bypass my A/C clutch relay, which turned on the A/C clutch. A/C clutch will not engage with just the relay. I replaced the relay with a new one, same results. So now that I know the clutch works by using a paper clip, where do I go from here?

Good afternoon,

I attached a wire diagram for you to view. The power for the control side comes from the same power as pin 30.

Do you have a test light or voltmeter to do some testing?

Hi there,

The way the compressor is set up it cannot run in reverse. So if you have a cooling problem I would have the pressures checked and if the com is not engaging at all you may have a leak in the system and the low pressure switch has activated isolated the compressor circuit.

Will the belt break and stop the car from running if you drive it when the compressor is out on the air conditioner?

HI if your compressor is makeing a noise and you have a serpintene belt. Then yes it can lock up and break the belt. But if your aircondition compressor has a single belt that runs only the compressor then no prob. Billymac

With A/C running my car in drive stopped at a stop light, foot on the break I can feel my car jerk and watch the rpm's drop and surge back up again quickly. I was wondering what on the air conditioning unit would make the car drop the tach slightly and jump back up again This only happens when the car is under a load in drive or reverse with the A/C on. With A/C off or the car in park there is no problems. Something on the A/C is what I am thinking and is it replaceable by itself because the A/C work great very cold, so I really was hoping not to have to replace the whole compressor since it works so good?

Hi there,

Thank you for the donation,

On the end of the inlet manifold is the A/C idle up valve, this picks up the engine revs slightly whit the A/C on, I would say that this is not working, get your mechanic to check it out, it may only be a broken vacuum hose or a faulty valve, start here.
