Have system evacuated and charged system is clogged up
where is my cooling fan relay controll circuit located in a 1997 Chevy lumina, 3.1 engine
yes
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
system running hot fans not running
Was unit evacuated before recharge after compressor replacement?
You'll need a vacuum pump that is used by AC service technicians.
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.
