Question about 2001 Ford F350 Super Duty SuperCab
I have a 2006 F350 powerstroke diesel and the blower for the heater only seems to work on the 1st level, cranking the dial to 4 (maximum) does not increase the heater output. Is it my blower motor that is toast or is there a power regulator that may be not working?
Change out the resistor for the fan motor it is next to the fan motor on a red plate in the air box

you may have a bad plug wire to the back of the alternator you can test that with a light tester but when you replace a alternator in a diesel at start up it takes about 35 secands before the unit will kick on

look for a fusible link out. You need to check for output on the alternator that you installed. make sure the batteries are fully charged before that, otherwise its not going to read right. start from the source. also, you can disconnect the batteries from the sys and do a continuity check on the wires in the loom, so you can see if current has a path, or if you have an open circuit. hope this helps

The first thing i would check is the Glow Plug Relay. Depending on your engine there should be (2 solenoids, or just one) sitting on the top front a little to the right of center. (right bank of engine that is) If you have 2 of them one should be smaller and it is the one furthest to the rear of the engine. It controls power to your glow plugs for cold start up. When you turn the key to the on position the 2 larger wires should both have power. When the ignition is off only one wire should have power. Check this if you do both these tests and only one wire has power with key on or off then you need to make sure that the key switch is sending power to the solenoid. Do this by checking the smaller wire with key off. It should not have power and then with key on it should have power. If this is good and test one is bad then the relay is bad. Note This is not true for the larger realy that sits furthest foward on the engine. The bigger one. This test will not work for it but it controls your intake heater. On another note: This is a timed circut and will "kick out" after about 1-2 minutes. In otherwords it does not stay on all the time that key switch is on it will for for about 1-2 minutes then shut off! Next would be your injectors are getting weak or bad and even your HPOP could be getting weak. or glow plugs in engine are out, In otherwords there are alot of possibilities causing your problems If you are getting a misfire code for your injectors then you may have some weak or inop injectors. Any way this will give you a pretty easy test for the most common failure which is the Glow plug relay. About 35-40 bucks at your local auto parts house.
