Avoid a trip to the mechanic by trying to troubleshoot problems yourself in your Toyota Tacoma. Air conditioning problems are quite common, but can often be quite simple to diagnose and even fix.
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.
Check the coolant levels if the air seems to run fine but does not get cool. The coolant reservoir is under the hood at the very front of the vehicle in a white plastic container with a cap. Lift the cap, shine a flashlight into the reservoir and look at the side to make sure the level is more than the low line but less than the full line.
Adjust the climate controls on the dashboard. If they seem to work normally but do not increase the air flow, then it is probably a blown fuse. Find the interior fuse on the left side of the dash to the left of the steering column.
Listen for the normal blowing noise when the air is running to increase when air is turned to high and decrease when air is turned back low. This indicates the blower motor and fan are working correctly.
Get help with the control panel if the climate controls do not work at all. Getting to the control panel of a Tacoma is very complicated and needs to be done by a professional.
