Good news is that you don't have any control modules etc to deal with. Check for power using a test light. Start by checking the actual bulb sockets and all fuses. Make sure the socket grounds are good
(if there is power at the center contact for a bulb but the bulb does not come on the ground is bad).
Also check the light switch itself to make sure power is coming out to the wire for those lights.
An easy way to find which wire from the switch is for those lights is to connect battery power to the hot wire of any of the running light bulbs and then check the connector at the switch to see what becomes hot (has power) that did not before you did that. No power there tells you that there is a disconnect somewhere in the harness. Trace the wire using the test light as a probe to see where the power stops. If that same wire isn't hot when connected to the switch with the lights on, likely the switch itself is bad. (test done with "test" power not connected to the harness)
Never use this test method in any newer vehicle or you can damage control modules.
Any questions about what you find, just ask.

I have a 99 Jeep Grand Cherokee Limited i have brake lights that work when i apply brakes, but as as soon as i turn my headlights on the fuse blows and i have no working tailights with the headlights on. ...


There is definitely a short in the park lights system. Did you just have a radio installed....since the illumination wire sometimes gets grounded and will cause that fuse to blow until you fix that wire.

I have a 1999 jeep grand cherokee and the brake lights wont work


there's a possibility that it might be the socket that the bulb actually goes into. my break light did something similar to that. the socket only cost about 8 bucks from the dealer.

I did this to a 1979 CJ-7 I had and also used 87-95 model leaf springs on it cause they are softer. It is not a easy thing to do because you have to be very careful to keep your caster and camber angles to the stock angle to get the Jeep to drive right. Check with Rubicon Express, they make a kit to do the spring over that has all the parts to keep everything in alignment for about $450 if I remember right. It would be well worth the money to have a Jeep that drives like it should.
