I have a 1998 concorde and the AC, signal lights will not come on at times. I have to wiggle the key on the ignition switch to get the AC to work. It is getting worse and at times I have to lower my steering down. Is this an ignition switch problem? Can I clean the contacts or what? Help Please!!!

 

also the abs light comes on when this happens.

 

Another note my windows will not work either. I need the experts to chime in and help me with this. It took me 10 minutes today to get it working. I had to keep slamming the tilt wheel and wiggling the key. It stayed on for a while and quit again. Help Please!!!!
