A/C systems are a fickle breed.

The moisture-absorbing "desiccant" in the accumulator or receiver-drier is supposed to prevent this from happening. Most of this debris collects in the condenser where it can cause blockages that reduce cooling performance.

You are most likely correct with that diagnoses. We have an air conditioner troubleshooting flow chart if you would like a step by step approach to air conditioner troubleshooting.

But the underlying reason for the fuse blowing in the first place needs to be identified and corrected to prevent the same thing from happening again.If the magnetic clutch is receiving voltage but is not engaging the compressor, the clutch is defective and needs to be replaced.

We got the 12v socket car use air cooling fan from www.amazon.com/dp/B010CESJTC , it helps so much that now we are OK to keep the weak air conditioner now for the summer. If there is a fault in the control system that prevents the compressor from increasing its displacement when more cooling is needed, there may not be enough cooling output to keep the driver and/or passengers comfortable. 0000003570 00000 n 0 items.

Reply If the leak is small, sealer can often save you the cost and labor of having to replace an expensive component.

If your car ran on Freon R-12 from the factory and you have the means to purchases it you can use R-12 or Freeze 12 to get maximum performance.
