I have premio 2007 X. the problem exist in AC , ometime is get cool and some time it get very hot. so need help to resovle the issue. Thank you

You might check your cooling fan at the radiator; it may not be running. If it's not, track it down (fuse or thermal switch) and fix it!

Gear oil level is even with the oil fill port. Just fill it until you can insert your finger slightly into the port and feel oil.

Be sure you check engine oil level often. The low oil sensor will disable the ignition. If you turn A/C on the cooling fan should run continuous, Check the fan relays. Make sure coolant level is correct at recovery bottle, never open radiator cap. A scald hazard exist, be careful. This car is old and complicated, and is beyond your skill level to repair. Try to inquire here for advice, whenever possible. Don't throw good money at bad money

NO,
replace the compressor only with an original Toyota part from the company Nippondenso only....
everything else is junk....
better change this silly mechanic...

It sounds like a heater blend door issue inside the heater box that is actually not closing all the way to allow either cool or hot air or visa/versa.

I dont belived having bigger radiator make your ac unit run better although radiator has nothing to do with ac beside colling your engine. If that was an issue to all cases, i think GM would have recall all of their envoy due to cooling issue, that's not so. If the car has been running fine since it was band new and now it started to have this cooling problems, I dont understand how can one come up with and idea that the radiator is too small, that dont make sense to me. Your eveporator sit in front of your radiator it may not have good flow of air movement to cool down the hot gases in the evaporator, maybe fan clutch is not working properly keeping the fan run at constant speed. The unit mabe also low on feon and not having enough feon in the systems causing your systems not to run properly. Low pressure or low feon will cause the unit also to run poorly and will caused the pressure switch to cut compressor on and off more frequent. Have the pressure tested and filled if need first. being 2003, if with high miles; its it good time to also have your thermostat replace if you never have it done. Hope that help some

are the cooling fans running when ac is on ?if not this is ur problem,,,if they are on then u have a temp door in the ac duct system that is closing if it is an actuator motor u will have to replace it ,if it is vacuum,check for a bad vacuum check valve or bad vacuum hose near fire wall(near windsheild)
