97 astro van ac problem

I'm not sure but its not the radiator fan. It is the fan that blows the a/c inside the car. I didn't know that there was more than one fan...
I could call it the blower........
Does that help?

Yes that helps a lot.
The front main radiator fan can come on and off of it's own as it is operated by a thermostat switch independent of the ignition.

You most likely have a short on the switch that controls the speed of this fan. The unit holding the switch will need to be taken off to check. This is not a real easy task, but achievable if you take your time finding all the clips etc.

Radiator fans won't come on while van is running

Start the car and turn on the AC to max. Do either of the fans run with the AC compressor engaged? Also, there is a temp sensor for the fan circuit but I don't know exactly where it is located on that vehicle.

My 97 Astro van is overheating after flushing radiator and changing thermostat. What can it Be?

did you burp all the air out of the system.

With the engine cold remove the radiator cap. Top off with coolant. Start the engine and let idle topping off coolant as necessary. When the engine is fully warmed up and you feel heat coming from the radiator fan replace the radiator cap.

check radiator fan. it may seem to work but they tend to blow but not as fast they should. one way is to remove it and connect it to a 12 volt source. it should try to lift off the ground or houver. if not that check thermostat and relay to fan. also always remember to replace thermostat they are cheap. and it never hurts to replace it. mian thing is to check fan and see if is blowing with as fast as it should. radiator shops can do this for you . you may want to remove the fan and take it yourself to save money

Heater Core in a 1998 Chevrolet Astro Van in quuestion... after replacing water pump, thermastat driving arround the block my van is still over heating there is also no heat comming out of ac what can i...

Start by double checking the coolant level. If this is good then, what I know of the way these things are made, purchase a chemical flush (from any auto parts store = $10 and add it to the system with the heat on high in the cabin. This will also help flush out any air bubbles. Drain and reill with good, clean coolant and distilled water (less minerals and contaminants which plug radiator cores). Do you notice the any fans coming on when the A/C is applied? If so... great! The very next to do is whilst the engine is running, wrap a rag around your hand, grab the fan in the front of the motor. Now don't worry, you will not get your fingers chopped off! Just make sure your rag doesn't get caught in any belt. If the fan stop right away and there is no felt resistance, IT IS FAULTY!! It must be replaced. Very and an inexpensive repair. This the responsible for engaging the fan blades the pull more air into the engine area via the radiator. Common fix. These do wear out!! Let me know if you need to change the fan clutch.

Every time I turn on my A/C unit in the 2003 Astro van it blows a 20 amp fuse inside. It also takes out the rear window defroster, no fans, all on the same circuit.

probably have a bad compressor clutch coil. unpug the compressor and then turn on the ac if the fuse does not blow the problem is the clutch coil, if it still blows you will need a wiring diagram to sort it out.

'97 Venture Van. Fan is not blowing no matter

Test the motor first, The wire to it is a hot positive wire and the motor's housing is the ground. If that works ok next check the resistor to see if its burnt out. Did you look at your fuses first?

Looking for location of bcm on 97 astro van dash

The BCM is located immediately above the heater controls inside the dash on my 2004 Astro. I know it controls the headlights and locks but not gauges. Haynes says the gauge fuse supplies it power....but I'm not going to bank on that one.
