you need a new blower motor resistor
the fusible link is in the fuse box in the engine compartment. you will see the large fuses that should be black and yellow with a clear top piece. I just had a fusible link blow on mine and just replaced the 80amp one.
The pressure of the sun causes the wind to blow.
have u had your alternator checked?
your truck blue smoke when it burns oil, or transmission fluid.
Detonation
buy a cummins
i have the same problem with a 90 chevy truck im was told to blow out the lines to the cooler rad. in the front grill #2 its the springs in the front pump
the winding in the fuel pump is more than likely burnt out, or the brush's inside it are stuck, you would be safer replacing than atempting to repair
I think there could be two main causes for this. I'm guessing you are referring the 100 amp fusible link...looks like a regular fuse, only larger? Age is one cause. Also, you could have a short somewhere in your electrical system. Did you use jumper cables lately? If those are reversed while jumping someone else off, you can blow out that fusible link.
why does fuses keep going out
It can.
