2007 dodge nitro so the fuses for my door locks and wiper pump keep blowing. Took the fuse box out checked all the wires. There is no exposed wires or wires crossing. Anything else it could be.

What # fuse's J5 25amp , J4 25amp , M 30 15amp , M13 20amp M33 10amp . All these fuse's are power supply's for door modules and to the wiper / washer switch . The washer pump is controlled by the totally integrated power module . I suggest you google TIPM - dodge totally integrated power module . Chrysler , Dodge , Jeep all use this componet . Also watch youtube videos on finding a automotive electrical short . That's what you have a direct short to ground on those power supply circuits

All park lights and dash illumination lights not working.

Sure you can find wiring diagrams , if you are in the States you can go to free wiring diagrams . But having factory service information from alldata or identifix Identifix Direct Hit online vehicle diagnostic system tool review is a lot better , shows pictures of ground location an gives description how the circuit works ,Pin point tests etc... I would suspect the switch before a ground . Check power at the switch an after the switch !

I have a 1995 jeep grand cherokeeand im not getting any power to the climate control panel

If you have checked the fuses, you may need a shop manual to have the wiring diagrams necessary to troubleshoot the circuits.
It looks like power comes from a 25amp fuse in the box.

Blower wiring diagram in a 1994 jeep cherokee

Well, not exactly.
The blower switch gets power from the control panel that gets power from the 25amp fuse in the fuse box.
The wire from the fuse box to the control panel is black and tan, the wire from the control panel to the fan switch is yellow and brown.

{: ) Check out the ST/LP fuse(25amp) at the underhood fuseblock. Also the VEH STOP (15amp) and VEH CHMSL (10amp) fuses at the fuseblock rear. If the center high mounted stop lamp is also not working, and you can't get any 12volts on either stoplamp bulb sockets, then most likely causes are the fuse, stoplamp switch on the brake pedal, and a faulty wiring.
If the center stop lamp is working and both sides are not, then the trouble can be isolated on the wirings or terminals of the two bulbs on the sides.
Wish you luck.

2000 Chevy Cavalier Z24 Convertible- Had intermittent control of passenger window. Pulled up dual window switch assembly from center console, checked connector for tightness and now the driver's window...

I have the diagram, brown wire is hot in run or start.It's controlled by a 25Amp fuse as a circuit breaker.It's been my experience that a broken wire in the wiring harness between the door and body is the usual cause of "intermittent control"of power windows.The colors of the motor wires are Dark Blue and Brown (drivers door),Light Blue and Tan for right side.If you have voltage at the motor and it doesn't work it might need replacement.Especially if your dome lights dim when you try to operate the window switch.The switches are disposable and not very serviceable.There are some tabs you can pry up to get to the inside of the switch,Warning: the contacts just lay there on pivots and will fall out if your not carefull.If you do open your switch and see any thing that's black or burned the switch is finished,and need replacement.Sorry I can't be of any more help!
