When I turn the fan on for the h/a sometimes it will come on. I have to turn the key on with the fan on hi, have to do this several times before it will blow. I can do this 5 - 10 times and when it starts blowing just leave it on high. Sometimes the running lights will not come on. Its getting worse now the a/c will not cool at all. Not sure if this is a relay or loose connection. Where do I look for a loose connection. If its a relay where do I find that also. Also having problem with key not completely turning off car and will not come out of ignition.

Need all the assistance I can get.

The relay(relays) you are looking for are in the glove box and are a pain in the butt to inspect. One relay is grey and the other is black. I thought mine where bad. They weren't it was the female harness that has the wires going into it that were losing a connection. Mine was the red wire. You will have to take the lid on the glove box out.5 screws, torx bits on the bottom of the lid. Then you will have more room to work. But from the sounds of it. It is probably the ignition switch. Also, a pain in the rump to mess with. And it sucks. But this is a process of elimination. Good luck :)
