How to troubleshoot 1997 Chevy Geo Metro it has no power to heater blower or air conditioner compressor flat visual fuses good the black four prong one inch rectangular under hood not sure what next?

If the blower motor is not running on either heat or cool, then the motor may be bad. Also the blower motor has a fuse. Another possibility is a defective blower motor resistor pack. Are you sure the compressor is not working and not just the blower motor? "Wirewilly" Here I repeat Fuses have been checked both under the drver side dash and left side under engine hood. Four prong relays how do you resistance check those? Yes the blower and compressor are not receiving voltage! When i first discovered the problem I thought bad blower motor so i tap on the motor like many no good GM electric recent 12 volt motors too see if it would free up, then took a voltage reading its dead no incoming volts for the blower or the compressor causing it not engage!So it should be a related electronic controling device for both A/C and heater! The best way to check a 4 prong fuse is to just substitute a known good one. I would suspect your blower motor problem is the resistor pack, although the switch itself could also be bad. A bad switch would account for no voltage at the compressor. See if you have voltage going to the resistor pack. If so the pack is bad. Good luck.

Why does the air conditioner not shut off but the blower motor does?
compressor contactor is bad. probably stuck in the closed position.
What if the AC on your 97 5.7L 4 door 4WD Tahoe blows very cold but does not blow powerfully even if it's set on high?
A vehicle air conditioner has two basic components; the compressor, and the fan, or blower. If the compressor is working, the air coming out of the vents will be cold, but if the blower is not working, the air will not come out very fast. Hot wire the blower to the battery, to bypass any fuses or switches, and see if the blower will run. If it does, but will not run when connected normally, check the fuse for the blower. If it is good, you would be wise to take the vehicle to an automotive electrical specialist to have them troubleshoot it.
Does air conditioner take a lot of power from battery?
With an auto air conditioner, the main power consumption is by the compressor. The compressor is driven mechanically by the engine, not the battery. Electrical power is used for controls, and to power the blower fan.
Why did your air conditioner stop working on 1984 corvette?
Blown fuse Loss of freon Does compressor run? Does blower motor work?
How do you reboot car air conditioner compressor after having work done on my car that required disconnecting the battery the air conditioner compressor doesn't kick in blower fans work fine thanks?
That should not be required. It sounds to me like something was left unplugged.
Does your home heating system use the air conditioner compressor for air flow?
No, the compressor only draws out the heat from air. The blower motor either blows warm air or cold air.
Where is the fuse located for the air conditioner compressor on a 1991 Oldsmobile 88 royale?
fuse #5 on the relay panel on firewall left and above blower motor.
Central Air running but no air?
If you are not getting any cool air, the compressor may need recharging or replacing. You will need to call a repairman.
Why does your air conditioner fan go on and off ford e250 van?
your air conditioner does not have a fan. you have a cooling fan, a blower motor for the passenger compartment, and a compressor clutch. i don't know which one your talking about. but if it is the electric fan for the cooling system behind the radiator then there is either an overheating issues, or a short causing the fan actuate. if it is a blower motor for the air vents. more than likely the blower motor or resistor is going bad. if it is the compressor clutch "fast cycling" then you are low on refrigerant and probably on your way to a really expensive repair.

What is the difference between a BLOWER and COMPRESSOR?
There is no difference. A blower is just a term used for a supercharger. A compressor is any machine that compresses a gas for many different purposes. A supercharger in its many forms is a type of compressor
What is the humming sound you hear from your air conditioner fan blower?
The compressor working to remove the heat from the air, but the blades could be dirty if the unit is old which throws off the balance of the blades and could cause this.
1993 MB 190E your air conditioner does not blow any kind of air you can hear the compressor kick in.What could be the problem?
The blower motor is probably busted, or the blower speed switch could be busted as well, if that isn't it could be a fuse for the blower motor I would check that first and save your self alot of time and money.
