Air Conditioning Problem On 1999 Corolla



My air conditioning is not working anymore. The compressor clutch does not activate, the second rad fan does not start.

No power come to the clutch wire when air is ON... I have checked the 2 one contact relays by switching them with the horn one, they are ok...

Anyone can help me with this ?

Most likely, you are low on refrigerant. When the system is low, the low pressure switch trips and cuts power to the a/c system. Try adding some 134a refrigerant.

you have a leak, lost refrig, the pressure switch has stoped the system from activating to keep the compressor from being damaged by lack of should have the leak repaired before having it fully charged and paying for a full charge.
