hi guys. i am new to this forum. I own 99 cherokee, but i dont know anything about cherokee. I have two problems. First, My airconditioning is not working. I found out that one of my radiator fan is not working. I brought it to MIDAS to get it fixed, but they coulnd't find the cause of it. They said that it could be my fuze, but it could be other. Another problem: nowadays, whenever i am driving my front end of my cherokee shakes with no reason. My handle moves right and left (harshly), and my whole front end moves right and left harshly,.. After 5 to 10 secs. it goes back to normal.
It 's been three years since i changed my brakes. Is it b/c my brakes are worn down? or is there any other problems that i should check.
any help will be great!

Check this for the shaking going down the road

The air conditioing system proly has a leak and no longer has any coolant in it.

Run a wire from the aux fan to the battery to make sure it still works.

if the fan isnt working, the ac will not work, it wont even turn on if the fan isnt operational

but on the other hand, no freon-no work also

The electric fan is made to go on when the A/C clutch kicks on. If the 134a coolant is too low then the A/C will not run (clutch will not engage) and neither will the fan. Get the A/C checked/charged and you will most likely see that the fan is ok.

thanks for the reply guys. I got my freon filled, But i will go check/and charge my a/c.. I may sound stupid, but when you guys say a/c or 134a coolant. is that the engine coolant ? or something else. thanks again.

134a is not engine coolant (ethylene glycol ) it comes in compressed bottles . and is usually injected at the compressor via shrader valves or the older style valves (can't remember there name)

you should get it charged professionally because they will check for leaks .

by freon do you mean your ac charged , freon would be 134a

This is a good tip because they will have the correct equipment to properly evacuate the A/C system before adding the R134a Freon. They can also add a dye that will make even small leaks visible under UV light.

Engine coolant (antifreeze) has nothing to do with the A/C system.
