How to Diagnose a PT Cruiser AC Problem
In your Chrysler PT Cruiser, its air conditioner offers you a cool feeling in summer. On the other hand, if you don’t use it on regular basis it can have various problems. Cruiser’s A/C unit is basically made up of three components i.e. the air compressor, the drive belt plus the HVAC integrated control unit. To avoid any difficulty you have to know how to diagnose a PT Cruiser A/C problem. It is quite a simple task and can be carried out in almost fifteen minutes at all.
Things you’ll need:
The only thing you will require is:
Step 1:
Begin with opening the hood of your PT Cruiser and there look over the belt on the A/C pump. A broken belt will obviously prevent the compressor to work. Although it is a drive belt so test out the entire drive belt on the front of the engine to get to any indication of wear or corrosion. After that, check the teeth of the belt. If you find the belt teeth damaged, immediately replace them to ensure that the belt is driving the compressor correctly.
Step 2:
Now turn on your vehicle. Next turn the A/C on full, furthermore set the fan speed to “high.”
Step 3:
Now feel for the cold air being blown into the cabin. If you did not find the A/C blowing cold, then there is certainly a problem due to a damaged compressor or else a lack of refrigerant in the cooling lines.
Step 4:
Now take out the blue cap on the low pressure line. Remember that only low-pressure has a blue cap running out from the A/C compressor to the firewall.
Step 5:
After that, place the pressure gauge over the top of the valve on the low pressure line.
Step 6:
To ensure that the pressure in the A/C lines is lower than the red mark on the pressure gauge, unbolt the check valve on the pressure gauge.
In case if you find the pressure falling within the green band on the pressure gauge; it means that the A/C system is pressurized i.e. there is refrigerant in the lines. If you did not feel cold air blowing in the cabin, it indicates that the compressor has failed. Low pressure or no pressure in the lines indicates that there is a leak in the lines.
Step 7:
If the compressor leaves to work it means it has leaks somewhere. In this case, contact a professional to check the lines. If there is not any leak, you have to replace the compressor at all.
