Welcome to Justanswer ! my name is XXXXX XXXXX i will do my best to assist you with this problem
so the A/C compressor 10 amp fuse shows NO volts on either side of that fuse testing that fuse in place through the little openings in the tops of that fuse ?
correct the 10amp fuse in the dash is good the fuse in the PDC power distribution center under the hood has no power even when you pull the fuse the connection in the PDC have no power loss of current,
correct no power on either side.
your meaning the 40amp fuse under the hood correct? If so then you mean I need to pull the fuse set the multimeter to dc volts an check the contacts.Should get 12 volts does that then run to the relay then the 19amp fuse in the box? It appears there is a jumper from DRL to the relay above it can't make out what it is but its got a dog gone resister in it was wondering is that factory or a recall or just shade tree mechanics?
wow it sounds shade tree if there is a random wire there with a resistor in it
the reason I need you to test that under hood 40 amp fuse is the a/c 10 amp in the under hood fuse box shows NO voltage either side
if that 40 amp fuse shows power both sides of that fuse testing that fuse in place through the little opening in the tops of that fuse there is an internal fuse box failure
as that 10 amp fuse should have power to it all the time and it gets its power internally inside the fuse box the SAME power as that 40 amp fuse gets
so if the 40 has it ( it should if the engine will run but we are confirming to be sure ) and the 10 does not the under hood fuse box is bad internally and needs to be changed
and I will bet that random wire you see was someone jumped something in that fuse box due to another fuse or power is missing and they jumped it with a wire as the internals of that fuse box where acting up before this a/c problem
that under hood fuse box has big battery power coming into it then that big power is shared to all the fuses
I hope this make sense to you and you understand what im saying
if you have any questions please ask
even after you rate us here at justanswer you can always get me back through this post with any follow up with this problem anytime !
so why is there power to the fuses at the dash if it starts under the hood wouldn't it not have power either? Also would it hurt or back feed the circuit if I put 12volts straight to the compressor?
the power is split up internally on a common bus bar circuit board set up inside the fuse box and some or one or a bunch can break and then fuses or a single fuse will not get power but the ones still connected will get power
yes you can run power to the compressor but make darn sure you fuse that wire with an inline fuse most autoparts stores sell inline fuse holders and just plug in a 10 amp fuse and use an ignition power source ( power only when the ignition key is on and the engine is running ) do NOT wire it power all the time ! as you turn the key off and it still will be activated will wreck the clutch in the compressor and kill your battery over night
