In my 95 ford ranger i keep blowing fuse 13 and maxi fuse 8. I have no brake lights or turn signals.

Fuses blow because there is an overload on the system. If the fuse blows when you step on the brakes then there may be a short in the wiring from the brake light switch to the lights, abs module or turn signal switch. If the fuse blows when you turn the key on then there is likely a short in the wiring to the brake light switch. Basically you will need a wiring schematic to check the wires at the switch and at each of the loads. Also verify that the fuse is supposed to be a 10 amp fuse. Hope this helps

type diagram you want into google and click images may be there worth a look

If you keep blowing the brake fuse than you have a short in the system. Unplug the brake switch. Install a new fuse. If it did not blow than the problem is after the brake switch. Next unplug the turn signal switch, then plug the stop light switch back in and press the brake pedal. Did the fuse blow. If not than the wiring is good in between the two switches. With the turn signal switch disconnected use a jumper wire in between the light green wire (power from the brake switch) and the orange with light blue wire (power to the right brake lamp). If the fuse blows than there is a short in the right side brake circuit between the plug in and the rear socket assembly. If the fuse does not blow than jump from the light green wire to the Light green with orange wire (power to the left brake lamp). If the fuse blows than the problem is in the left hand brake wiring circuit.

short circuit in the multi function switch in the column.

i had this problem with my 1999 jeep grand cherokee laredo with the brake lights it kept popping fuses right after the ignition was turned on try putting a higher amp fuse in place of the old one that keeps blowing then check for shorts to the starter and check grounds and wires and also the transmission issue check the fluid and then if the fluid is fine change the transmission filter the filter may have not gotten replaced when the transmission was rebuilt and may be clogged or dirty

check if you are using the right fuse for one and then check your wires for nicks or any thing that doesnt look natural for a wire

Bad earth connection.Clean or replce wire.

you might have blowed blulbs check that also there might be what is called a fuse link in the wiring

your problem is attributed to the turn signal switch , both the left and right turn signals go thru the switch as well as the brake lights , it is a common problem with these cars.
