Oga Mosbus, my AC is still chilling o, till date.

Could it be that, all my AC problems are now a thing of the past?
All thanks to GOD,pls always make sure you check your cabin filter at most every 3 month depending on how often you drive and your environment.
Thanks.

There's no cabin filter, last I checked, it's been removed.

You are endangering the life of your evaporator.

so I have my evaporator recently replced, and ac shaft seal repaired.the technician doesn't have a vacuum pump, thus didn't vacuum it. this is about 4wks after the job, car chills ok, have seen another technician who has a vacuum pump, would you advice me to go and have it vacuumed and refilled properly

lol, was wishing you would not say this, I would be sad, if the super cooling fails because of this.
you feel the air inside would cause the system to develop a leak in the future, and is even preventing my ac from chilling even better?

is any refrigerant beta?, ie the big 5kg green bottle of gas vs the small 1kg bottles, is any better than the other, I intend to refill with Cheb
refrigerant, as its said to be better than maxxron

The empty space, but I can't find any hole sef and air didn't pass thru when I put on the AC now.

I'm not doubting you, just trying to let u know what I observed.

Hi Mobos, thanks for your support so far. My AC was working fine I just felt it wasn't cool enuf so I went to refill the gas. Immediately I refilled it, grew compressor started working intermittently. I mean the ac fan continues to blow but it only blows cold air at intervals and at overall the car doesn't get cold at all.

My AC blows cold air for few seconds and then blows ordinary air, blows cold air again and then ordinary air.

The cooling is intermittent and this started after I refilled the gas by a road side technician.

Overfilling of gas can cause that,and also check radiator fan rotation.

Thanks Mosbus. My observation is that the compressor stop intermittently.

What should I check in the fan rotation and how do I solve overfilled gas issue?

Drain the gas from the high side,and for the fan.The speed should increase after 30sec-2mins when ever you put on the ac,and also some cars radiator fan increases immediately you put the ac on.so it all depends on how the manufacturers of your car design the electrical wiring.
In addition some Rewire's do mistakes when ever they are connecting your fan some time instead of blow the normal direction it will be blowing the reverse way.

Hello Mosbus,

I need your advice on the air conditioning system of my Camry 2000.

The A.C does not cool while stock in traffic and improves as soon as the car moves. Also, the A.C switch on button light (green light) blinks while working and A.C does not cool like I would have wanted.

My location is Ajah, Lagos.

You have low refrigerant in the system,and for the switch blinking,your torque sensor is faulty and you find that sensor under your compressor.
Pls tell your technician to check your compressor oil seal first if there is any leakage before any further check.

Oga Mosbus - I sincerely appreciate your efforts in resolving my EOD's A.C issues on Saturday and Sunday.

With the use of his latest sophisticated machine/tools, the A.C came back to life and is still chilling ooo grin grin

A humble, educated and down to earth guy. He even came on Sunday to help correct another issue on my Compressor.

Extend my regards to Baba Blue (Chelsea Fan)

Compressor Replacement Without a Vacuum Pump

Evacuation Procedure

1 - With the new compressor installed, turn on the compressor and depress the access valve on the high side of the system. Monitor the pressure on the low side of the system. When the pressure is as low as it will go, close the access valve on the high side of the system and turn off the compressor. This process will take about 5 minutes.

2 – Charge the low side of the system to approximately 14 psi.

3 – Wait about 3 minutes for the pressures on the high and low side to equalize.

4 – Now turn the compressor on and depress the access valve on the high side. When the pressure on the low side is as low as it will go, let the high side access valve close and turn off the compressor.

5 – Repeat steps 2, 3 and 4. Note, on successive evacuations, the low side pressure will not go as low because of the absorption of refrigerant in the compressor oil and it’s slow release.

6 – Charge the low side of the system to approximately 14 psi.

7 – Wait 3 minutes for the pressure to equalize. Turn on the compressor and depress the access valve on the high side. This time, when gas is no longer coming out the high side access valve, let the valve close. The air is now purged from the system.

8 – Charge the system with the appropriate amount of refrigerant and turn on the compressor.

9 – Make appropriate adjustments in system charge if necessary.em change if necessary.

mosbus is this true?

I advice you vacuum the system if you replace any part.
All you need is have a vacuum pump and vacuum to 20-30 minutes.because there is no how you will change any part and atmospheric pressure won't come in.

I wish to thank you for your remote assistance in relation to my air conditioning system.
It's a month now and the A.C is still chilling. I hope to pay you a visit in your workshop soon.

Possible cause of black debris in your car air conditioning system.
1,clogged condenser
2,blocked discharge hose
3,wrong compressor oil type
4,bad refrigerant
5,low or excessive refrigerant in the system
6,lack of vacuuming the system before refilling
7,raditor fan failure
8,electrical issue
9,faulty evaporator thermostat
10,blockage inside the engine radiator.
