Good day gazzuz. I noticed that my AC is no longer cooling as usual in my Toyota RAV 4 2006 3.5L, I went to an AC technician to add some Freon, however the AC stopped during the recharge process and the light started blinking. I scanned it and its giving me B1422 ( Compressor lock). The technician is telling me the compressor clutch is damaged, but I have a feeling that he over added the Freon gas into the system. I really need an advice from you Sir.

The climate control ecu noticed the engine on, coil engaged but no rotation picked up by the rpm sensor on the VDC compressor. This will immediately throw a B1422 and disengage power to the clutch to ensure no added damage is caused by this malfunction.

So let's analyse.

Possible faults.

1. A Frozen compressor.

2. A faulty coil.


frozen compressor is a more likely cause.

What model of car is it.
Re: Maintenance Tips On Cars. by kcbaba007: 11:23pm On Dec 02, 2018
Boss, that button is not the issue, let me analyse it for u
When u press down d power button, and try controlling either of d windows from.d driver side, the clicking sound stops, but when u put off d power button, and try controlling either of d windows from d driver's side it clicks, I feel, a line has been bridged, and I feel d problem is coming from.the driver's side.

adanny01:


Come oh! There is a switch on the drivers door that stops all 3 windows from operating. The drivers window is excluded and this sounds like that button was pressed.

Press the button to turn it off then try again.
Re: Maintenance Tips On Cars. by kcbaba007: 11:24pm On Dec 02, 2018
I just have not been able to actually get where d problem is coming from

If you get clicks on the door you try to operate, it means there is power to that door.

I have experienced similar problem with my EOD but not on 3 windows like you, mine was just one rear right window. In my own case, the window stopped operating while fully down. Took it for repairs, immediately the winding mechanism was removed and plugged to power, it worked perfectly. Putting everything back it worked like magic at the workshop but immediately i left, it stopped again. An electrician later checked the motor brushes but they were not worn out. The was nothing to be done as it keeps stopping and starting at will. Because of the frequency of the problem especially stopping when the glass is down i disconnected the window for half a year. I knew how to dismantle the window and put it back.

Just like you, i only get çlicks from the window when it stops. The solution to my problem was greasing and cleaning the brush contact to amateur. Its over 6 months now and its still working when mechanics said i needed to buy a new winding mechanism.

Let me explain how the click works, the window is supposed to click only when limits are reached. The system has a something i cant easily explain like a "torque limiter" (my assumption). It works by way of knowing that the window has reached a limit when the normal force applied to move the window has been overcomed by a force stopping it. It clicks to stop supply of power so as not to damage or over work the motor. This means that in normal operation, the window clicks at the top limit as well as the bottom limit. My conclusion was that anything that causes the window to click when it has ample allowances to move is either from the mechanism or window rail. It means the system cannot overcome the force to push or pull the window.

In my own case removing the 3 bolts holding the motor housing in place will just allow the window to work like magic. If i bolt the motor housing back, it stops soon afterwards. So i localized my problem to the motor housing area. I greased the cable winder and the improved the brush contact making the motor stronger.

I suggest you take out one of the mechanism and try it without load.

I like your improvisation! I remember that one technician broke some small plastic that controlled the central lock while working on my rear power window once. cry

@gazzuz. My Corrolla 04's AC no longer chills as it used to.I repaired the compressor less than 5months ago and changed the air filter too.Also refilled the gas. What could cause the AC to have stopped chilling so soon?

I was going to suggest same as it has happened to me in the past. I pressed the button without knowing and unfortunately my window was down when it happened, I had to get a panel beater to get it up only to notice a few days later that the button had been depressed.

@kcbaba007 Would be nice to share with with us what you discovered eventually when you find the solution.
