I have a '87 Jeep Cherokee Laredo. Whenever the A/C or defrost comes on it will blow a fuse. I am a female so please be gentle with your responses! I put in the correct amp fuse and all that but this is the third time it's blown and the wires all seem ok, no open/bare/decayed or touching wires that i see. Please help! I really don't want to take it to a mechanic unless I must.
