I had the same problem with the mid 90s Ford Ranger I don't know if your turn signals are working at all.

SOURCE: dash and running lights not working

The dash and insrument illumination lights are both controlled off the same circuit within the headlamp switch. You can try finding a happy spot for the lights by very slowly pulling out the switch after the running light position and turning the knob back and forth, but, this is purely temporary. You need a new switch and it's very easy to change. If you disconnect the battery positive cable. Pull the switch all the way out to the headlamp position. After doing this reach around the back of the switch on each side and you'll find a small button that you can push in. This button allows You to remove the knob/shaft combination. Then just take out the 6-8 screws that hold the cluster face plate(or it may just pry off) and unscrew the collar that secures the headlamp switch to the dashframe.. The harness comes of in one piece and that's it. Good Luck Dana

SOURCE: have a 1999 bounder 34j

flasher and blinkers look like a small silver cylinder, maybe an inch or so in diameter. they are usually in the fuse box or somewhere in the dash. (in my 93 mustang the flasher is almost in the middle of the dash instead of driver side while the blinker part is inside the fuse box. now this is just the ones i've seen, yours SHOULD be the same, but i'm not positive. you said you found something with 3 wire plug in? that sounds like it may be it, but look for the cylinder like things first

My windows wont go up or down why?and my fuse in the cab fuse box 3rd one in the second row blows when i put it in why?and my dome lights wont come on


Your windows won't go up or down because either the motor is not receiving the signal to go up or down or the motor is incapable of moving the windows up and down. Your dome lights won't come on either because they aren't getting the signal from the sensor to do so or they don't have the power to do so. This leads us to your middle question (you didn't specify a vehicle model): your fuses are blowing instantly because you've got a short, and I'm willing to bet its a short related to the two other systems you say aren't working. Check all systems related to that fuse for a short, and then put the fuse in again once addressed.

My left turn signal works fine, why when I turn the right signal on it blows the fuse.


Remove the right front and rear turn signal bulbs. If it still blows a fuse take it to your mechanic to find / fix the short circuit. If it does not blow the fuse, replace the bulbs. You may of course also replace the bulbs one at a time to narrow it further as to which one.
