1999 Chrysler Cirrus: 8 IGN Fuel Starter Fuse Blows?

There is a short in wiring or over draw of current causing the fuse to blow.
Few basic testing and inspection is required.

This fuse protects several circuits and components so you will need to determine which one causes it to blow.

Try is testing procedure to confirm the fault:--------

Try to remove the fuel pump relay and crank for some time, then check if the fuse is still OK. if it is OK, then your fuel pump may draw too much current causing it blow. If the fuse blows even with the fuel pump relay removed, then your starter motor could be the reason/
There are several other components powered via this fuse, so you may want to remove the following fuses from the junction block ( instrument panel fuse block) : F17, F14, F15 . Then see if it blows when you start it
Try to remove the starter motor relay or just disconnect the small wire from the starter. if then Fuse is OK, then your starter appears to draw too much current.
The starter solenoid could be the reason if takes too much current.

The fuses located in the dash fuse box. But start from removing the fuel pump relay and then starter relay.

This details will help.

Thanks.

2004 Jeep Grand Cherokee Fuse Box?

The Power door locks and Power windows stopped working.
This both modules are controlled by same fuse.
The first thing in this case is to check the Fuse.
On 2004 Cherokee there are two fusebox panels.
There is a junction block containing fuses under the left lower corner of the dash, and a power distributuion center under the hood that also contains fuses.

Fuse #12 (50amp) in the under hood power distribution center supplies power to the door modules.

That #12 fuse does supply power to both modules. So check that fuse first.

In many cases its seen that wires break in the rubber convoluted boot between the driver's door and the body, so keep that in mind. Now the driver's and front passenger door contain door modules that control the windows and power locks. Both the modules getting faulty at same period is rare,so first check the fuse,but if its checked ok,then inspect the wires running from module to door locks and power window switch.
