Your location matters. If in Florida heat pump in more northern climes furnace & ac.
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
By a current pump you might mean an electronic circuit using transistors or an IC. These circuits often do not take a wrong supply very well and it might be destroyed.
do you have a heat pump? are you running unit in heat? if so and the steam is comming from outside unit, this is normal in the units defrost cycle
S=iv 460=115*i Therefore i = 460/115 i = 4 Amps
the selector switch is a vacume and electric switch that activates the pnumatic vents, ac and fan. on the back of the selector there are tubes that feed a vacume to the vent flaps and a three wire plug for ac and fan control. if you lose vacume the vent flaps stay in the defrost and floor position but the ac and fan will still work. on my sonoma the vacume line came disconected under the hood. the vacume feed exits the firewall on the drivers side right next to electrical harness.
They have no reset. An ac pump has no memory board.
I used a 1/2 gallon pickle jar and a hand vacume pump. Install two fittings in the lid of the jar and attach the hose from the vacume pump to one fitting. Attach a second hose to the other fitting and put it into the transfer case through the fill hole. When you pump the vacume handle it will create a vacume in the pickle jar and suck out the fluid. It helps if the fluid is warm, and you have to keep moving the hose around. I have used this setup to remove all types of fluids.
Things to check: Coolant level Heat and AC fuses Vacume leaks Actual operating tempurature of the engine.
you could take a vacume pump and pump it out that way or drain it all and only put the right amount back in
you may have a vacume problem.Most likely the vacume line thar goes from engine,through the firewall.This hose is made of a hard plastic.Over time,it will get brittle and break.That is where I would start.Look on the pass side of the firewall where the wiring harness goes through.That is where the vacume line goes through.
the vacume pump is located at the front of the engine, to the right of the crankshaft pully. it is between the crankshaft pully and the a/c compressor. fellow mill owner jim
Ac connector at ac pump I pull out connector and jump connector and blow out the ac fuse. I change out the ac fuse and the ac pump not engaging. What other problem could it be? The ac was working before I did this. Please help. Any help thanks.
usually a fuel problem. IF carborated bad accelorator pump or vacume leak. Fuel Injection systems check computer codes. Defective Map sensor measures incoming air. TP switch Throttel position switch, and or vacume leak.
The ac pump may be seized up.
Call an AC contractor
