- 2003 Ford Explorer
Haven't been on here in a while but I've run into an issue I know nothing about. After searching the forum and reading others post along the same lines I still find myself a bit lost.
I drive a 2003 Ford Explorer 4.0L with 220k miles. The thing still runs like a dream (Knocks on wood) but it hasn't had working AC since I bought it almost 3-4 years ago. It's finally become a massive annoyance so I've been looking into it. First thing I noticed was that the clutch doesn't engage. But spins freely by hand.
I checked the fuses and relays, all were okay. However in the diode connected to the system I wasn't able to get continuity, as if it may be blown. I'm not certain how large a role the diode plays is this circuit however.
When I jumped the pins on the relay I was able to get the clutch to engage and spin. I only allowed it to engage for a single second then I disengaged it again for fear of damaging the system.
Under the assumption that the relay is fine, am I looking at a bad "low pressure switch" or could it really be that it is just too low on R134a? If it is low, then how can I recharge the system without the clutch being engaged to create pressure and draw in the refrigerant?
