2004 Acura TL, I’m redoing the ac, I removed and vacuumed the system for 45mins for moisture etc, but when I go to add redridgerent the ac clutch doesn’t engage to let anymore in? I tried jumping the relay to have the clutch engage and nothing? Any ideas? Someone said it may be the clutch or the field coil but I’m unsure.. was working before because the ac was cold!

No. 1-1


I hot wire them directly to the clutch to start them up. If that doesn't work, clutch is shot
