If you reach for the A/C in your Toyota car in the middle of summer and all you receive is a blast of hot air, your A/C system may be experiencing a number of issues. However, you can diagnose many problems on your own, such as insufficient pressure in the A/C system or a refrigerant leak. Before taking your Toyota car to the shop for what could be an expensive visit, you can run through a few troubleshooting steps.
Start the engine and let it to run for a few minutes to allow the air to cool. Double check the controls to make sure the correct buttons are selected. This may seem simplistic, but human error could be to blame.
Adjust the climate controls. If they seem to work fine but have effect on the air then the problem is probably a simple blown fuse. If the controls do not work correctly, then the problem is probably with the control panel. If you cannot hear the sound that accompanies turning the air from low to high, then the problem is likely with the blower motor.
Check for a blown fuse. The interior fuse box is located to the left of the steering column in the dashboard. Remove the coin tray, and then remove the trim panel surrounding it. Use the guide on the inside of the fuse panel to locate the blown fuse and replace it with one of equal amperage.
Get to the blower motor pretty easily in a Toyota Camry. Unscrew and remove the glove box entirely. The blower motor is directly behind it. Unplug the electrical connection, unscrew it and remove it.
Pry off the trim panels surrounding the climate controls and radio to gain access to the control panel. Press the two fitting tabs in toward one another to release the heater control assembly.
