The fuse is OK and its not over heating, yet. Loren Champlain Sr Veteran / Moderator Nov 28, 2008, 6:23 PM Post #2 of 5 (1687 views) Re: Fans not working Sign In The electric cooling fan is controlled by the computer via a coolant fan switch, which tells the computer the engine temp. Many of these fans will not come on until the engine reaches 220-235F. (Another reason for 50/50 mix coolant..without coolant under pressure, you'd be boiling at 212F.

If cold enough out it might not?? T Loren Champlain Sr Veteran / Moderator Nov 28, 2008, 6:36 PM Post #4 of 5 (1681 views) Re: Fans not working Sign In I was kinda thinking the same thing, Tom.. Got up to a balmy 43F today. Brrrrrrrr. Windy, rainy. Leaves everywhere. arrggghhh. Loren SW Washington autojoe User Nov 29, 2008, 10:52 AM Post #5 of 5 (1667 views) Re: Fans not working Sign In year/make/model/engine size?Most tranverse engines electric cooling fans come on at a stop or in traffic because when vehicle is moving air goes through rad removing heat from cooling system.most people find out fans not running when temp gauge goes up or idiot light comes on.A scan tool would tell you what temperature the coolant temperature sensor is telling the computer.On newer cars the coolant temperature sensor tells the pcm the coolant temperature and then the pcm controls the cooling fan or fans through low or high speed cooling fan relays.if you let car sit at stand still with engine running and temp gauge gets to about 1/2 way about normal operating temperature and see if fans kick on.If you have ac turn the ac switch on and see if the fans kick on.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
