Just fix it the way it should be and carry a fire extinguisher even while removing all that crap, T repairguy New User Jan 20, 2015, 3:53 PM Post #3 of 4 (1365 views) Re: homemade heater blower motor set up Sign In well i need a quick fix till it warms up enough outside so i can fix it right Hammer Time Ultimate Carjunky / Moderator Jan 20, 2015, 4:35 PM Post #4 of 4 (1362 views) Re: homemade heater blower motor set up Sign In Your quick fix is buy another car. Stop with the nonsense you are trying. You know nothing about electrical circuits and you're going to end up starting a fire. You CANNOT run that blower motor with direct wiring and a toggle switch. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   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
