where is my cooling fan relay controll circuit located in a 1997 Chevy lumina, 3.1 engine
Check the relay.
Only when the AC is on.
the thermostat will make both fans become idle if it is not opening. this happened to me on my 95 3.1 lumina
I believe it comes on when the a/c is turned on but not positive
Not tightened properly? Threades stripped?
Get a professional to do it properly. Your welcome
Was unit evacuated before recharge after compressor replacement?
system running hot fans not running
You'll need a vacuum pump that is used by AC service technicians.
Try the rear side of the radiator approx. 1/3 down from the top
unplug the connector remove the screws holding it in place reverse procedure to reinstall
You could, but it would probably be a bit more effective just to fix it the right way.
There may not be one, My 2000 Lumina has a plug on the lower drivers side of the radiator that can be replaced with a petcock. Rather than do this I removed the lower radiator hose to facilitate flushing the cooling system.
Your Lumina 2001 engine light might come on while the radiator fan is working because the fan is turning too slowly, is damaged, or is not cooling the engine correctly.
A sure fire way: get the nose of vehicle up like on a incline on a driveway then remove rad cap and let idle for about 20 minutes. It helps to increase idle speed also to open the thermostat.
There are several things that can cause your Chevy Lumina fan to not work properly. The most common cause is a bad ground wire. Check the ground wire and make sure it is tight and free of corrosion.
Drain the water from your 1997 Chevrolet Lumina cooling system. Remove the water supply lines to your heater core. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
There are no general codes. Look at the serial number, call the dealer and they can tell you - after you ID yourself properly.
Drain the water from your 1993 Chevy Lumina cooling system. Remove the water supply hoses to your heater core. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
Hi,I have a lumina 95 which just recently had an air pocket after changing a radiator hose.I was told by a friend who is a mecanic to run the heater on high (hot air)which i did while on a trip and it seems to have worked.
Lumina village is in Romania.
my 97 lumina has the same problem. the user manual says that the security system is not working properly. it will not cause problems, but the system should be checked by a technician. hope this puts you to rest, it did me....:)
Remove the bottom radiator hose from your 1995 Chevy Lumina radiator. Put a water hose in the top of the radiator. Allow the water hose to run. Keep the water running until clear water runs out of the bottom of the radiator.
