Then in november i was involved in another accident causing a lot more damage to the front left of my bumper. The air con after my yaris being fixed a second time was royally effed was blowing hot air constantly.

From the first accident there was a scratch on either the condenser or the compressor and the block at the repairer said it may have jumped forward in the jolt of the first collison and stuffed it up somehow so i would be covered under my comprehensive insurance.

The bloke at the air con shop looked it over thinking it was the wiring or something, it worked for a week, he didnt tell me what he did. He just said yaris' are common for air con not working and it may be the computer system not letting the air con start up?
He is now saying the air con problem was not caused by the first accident when it first started playing up and that i will have to go to the dealer i got it from and will need to get them to do whatever and pay a shit tone so it to be fixed..

I have no clue on what the hell is actually wrong with it but i do know that it WAS caused by the first accident somehow. HELP!

The Yaris AC system is very basic and easy to diagnose. The most common failures are leaks (easily caused by accident) and bad pressure sensor.

Leaks can be tested by measuring the system pressure and doing the dye testing if the system has lost pressure.

The bad pressure sensor would be the one which is mounted to the aluminum tubing under the hood by the sight glass. That can be diagnosed using the toyota service tool and/or by seeing that the system is properly pressurized, yet the compressor quickly cycles off.
