I replaced my ignition switch in my 91 honda civic today and have since had no heat. The fan blows but it is cold/cool air at best. The ignition switch was in perfect working order as I took it off another of my civics before installing it on this one. I was wondering if there are any reasonable things that could have caused this such a disrupting a connection or altering something slightly in the area of the ignition switch. I would just like to figure these things out and take a look before I consider larger problems, which I am also very open to hear as any information will make these repairs much easier. Thanks.
