    The heater blowerdoes not work on my FJ40, The problem is I think with the resistor, everytime I connect it it blows my fuse, What could be the problem, I attach the image of the current status of the heater.

    Checked the resistence value, and says 0 ohms, whats the right resistance, should I only change the resistence and which cable should I connect to bypass the resistence and where only for checking if the heater motor is working.

    You need a 1 Ohm 50 Watt resistor. One sources is Allied Electronics. Ohmite Part# L50J1RO. Your fan should still run at high speed even if the resistor is bad. Make sure the fan turns by hand then unplug the connector from the motor and apply +12V and ground to it with test leads, it should run at high speed. If it doesn't run then you have a bad motor or possibly just bad brushes. Check the link for a heater refurbishment: http://www.globalsoftware-inc.com/coolerman/fj40/9A.htm
