2003 Ford Ranger Q&A

2003 Ford Ranger Question: The a/c is causing rpm to fluctuate when I put it in gear and keeps clicking.

When I put it in neutral or park it doesn't seem to draw down. Does someone know what is happening? Thanks for any help. -
Answer 1
The A/C system is short cycling because it is low on 134A. The clicking is the clutch on the compressor turning on and off. Get a A/C service done and you should be fine. -
