How to Troubleshoot the Air Conditioning in a Honda CR-Vby Contributor
You may be able to save a lot of time and money by trying to troubleshoot car problems yourself. Air conditioning problems are quite common, and might be caused by any number of things. Try to self-diagnose air conditioning problems in your Honda CR-V.
Start the engine of your Honda CR-V and allow the engine to warm up before beginning the troubleshooting.
Check the coolant levels in the coolant reservoir. Lift the hood of the vehicle. Find the reservoir in the very front of the vehicle on the driver's side. It is a plastic white jug. Lift the lid and shine a flashlight into it. Look at the side of the jug to make sure the level of the coolant is in between the low line and the full line.
Open the interior fuse box to make sure the fuse controlling the AC is not blown. The fuse box is found in a Honda CR-V by opening the driver's door and prying off the trim panel on the very side to the left of the steering wheel. The fuse needed is number 17 and is 7.5 amps.
Switch the air to hot to see if the heater is malfunctioning too. If neither the heater nor the air conditioner work, then there is a shortage in the wiring.
Adjust the air from low to high and listen for the sound of the blower motor to increase. Blower motors need replaced in ageing vehicles commonly. Find the blower motor in a Honda CR-V by prying of the lower foot panel on the passenger's side. Unplug the electrical connectors and pull the blower motor downward.
