Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Recharge Refrigerant

Use a refrigerant gauge to check the current refrigerant level.
If low, connect a refrigerant canister to the low-pressure service port.
Add refrigerant according to the manufacturer's specifications (approximately 1.5 lbs of R-134a).
Monitor the pressure gauge during the refill process.

3. Replace Cabin Air Filter

Locate the cabin air filter housing (usually behind the glove compartment).
Remove the glove compartment for easier access.
Unclip the filter housing cover and remove the old filter.
Install the new cabin air filter in the correct orientation.

4. Inspect and Replace AC Relay/Fuse

Locate the fuse box (refer to the owner's manual for location).
Identify the AC relay and fuse, and visually inspect for damage.
If damaged, replace the fuse with the same amperage rating and the relay with an equivalent part.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Set the AC to the highest setting and check for cold air flow.
