Q: Air conditioner clutch doesn't engage

asked by on August 01, 2016

My car’s air conditioner clutch isn't engaging. It’s been quite a while since I've used the A/C and it’s getting very hot where we live. I refilled the unit with a 14oz can, but the clutch still won’t come on. Also, I unplugged and tapped the air conditioner relay. Nothing happened, but I did notice that it was hot. I replaced an a/c fuse on the fuse box by the battery, plus I checked the interior fuses. There is corrosion around the exterior fuse box. Could that corrosion around the exterior fuse box be causing it not to work?
