A/c problem. I have a 2004 Toyota sienna van 83000 Km.Bought in feb 2009. I replace dust& pollen filter that time. Now when I turn on A/c when the temperature is warmer, driver side vents blow air like I turn on just fan but after 15 minutes vents start blow mild warmer air. Passenger side vents blow mild cool air at the time A/c is turned on but after 15 minutes these vents blow air like just the fan is on. I am not aware of anything related to electical and electronics. Please tell me what it is due to and how to solve this problem.

    Hi Jason,

    I am not sure if the A/C was working well before I cleaned the filters as I bought the van in feb 2009 that was winter time. However, I made sure if the A/C was working or not before purchase. A/C was working but I wasn't aware of how efficient it was since I didn't need to turn on A/c during winter time. Thank you for asking.

    it is prob just out of gas and has nothing to do with what you have done.Gas leacks in car a/c units are a very common fault. the person you bought it from prob just got someone to put gas in it to sell it without fixing the leak

Jasonjacob1 is right. If the air from the A/C is not cool, the only cause is low or empty refrigerant. This means that the gas that your vehicle uses to produce cool air is gone from the system. The solution is not to recharge the system but to locate and fix the leak, then recharge the system.

I checked all the fuses. No fuses are blown. The battery is fully charged & the electrical, lights, & radio all work fine. The 2004 Toyota Sienna van still doesn't even turn

Can be a bad contact in one of the cables. A bad contact in a switch or electronic switch. a bad relay, and a dozen other causes.
Please start measuring to where the power comes and where it stops. You are close to the car, we are not. For a correct diagnose use a multimeter and look under the hood.

Where is the dust and pollen filter located on a 2009 Honda CRV?

Hi Maria: Remove the glove box, then you will be able to remove the cabin air/pollen filter. If you need help removing the glove box, try You Tube and search "2009 Honda CRV dust and pollen filter replacement. You can purchase one from a Honda dealer online or aftermarket such as Rock Auto, etc. Take Care.

2004 sienna toyota van electric door not working

The first thing to check is the fuse that controls that door's motor. Look in your manual for the fuse chart. Determine where the fuse panel is and which fuse it is. Pull that fuse and take a close look to see if it has blown. If so, replace it with a new one of the same amperage

2009 Sienna Airbag on Drivers side is off.

I hope you did not purchase your Toyota used; one of the worst scams around is selling used vehicles with missing or useless air bags.  The replacement cost on these is in the upper 3 digits. Because of the possibility of triggering the air bag by accident, I don't advise that someone not trained should attempt to troubleshoot these.
