Cooling Fans Grand Am Cooling Fans Not Working 1. just unplug your ac pressure sensor, using a paper clip like picture here both fans will come on when ignition is on and car running, tape up clip and order a c refrigerant pressure sensor from a place like rockauto. share. improve this answer. edited mar 26, 2018 at 9:00. zaid. Re: 97 grand am cooling fan. for the switch to get hot there are 2 possibilities. 1) the switch's amperage rating is too low for your application. 2) you hooked up 12v directly to the switch without connecting a bleeder resistor.
Cooling Fans Grand Am Cooling Fans Not Working My 2000 pontiac grand am gt (6 cy 3.4l) has been having cooling issues. i started by replacing the thermostat and performing a flush & fill on the radiator. this didn't seem to resolve the issue the engine still overheats when at a stop. this lead me to suspect the fans, so i tested the fans themselves (independent dual electric cooling fans). The first thing that you would want to do is locate the fuse for your grand prix’s radiator fan and make sure that it hasn’t blown. if it is blown, replacing the fuse will only solve the problem for a very limited period of time. unless the wiring issue is fixed, the fuse will blow again. the wiring harness itself can go bad. It is just right here on the picture, take a look,! g103, g105, and the other grounds, cool no! i just find one corroded on the connector ( motor blower ) and the other on the motor blower resistor, green corrosion and a sticky connector, and find after 45 min on a runtime engine, the main fuse and relay circuit deffect by a hot relay, temp check innova 3340a or a temp gun, heavy wiring. Here are the most common ways a radiator fan can stop working: if the fan isn't running at all: blown fuse or malfunctioning relay. bad fan motor or wiring issue issue with the fan control module. issue with the coolant temperature sensor. obstructed fan blades.
