I have this 91 honda hatchback. The engine will die as soon as you let go of the key. So I replaced the ignition switch. Now, the car is running but the hot or cool air will not come on. The cooling fan sounds like its louder then before once its on. Everything else seems OK on the inside again. The lights in the dashboard are all back on after replacing the ignition switch, except for the hot or cool air. Please help.

If its just the noise and the cold or hot air is coming out. I had the same problem the fan was loud and I had to change the fan bearings. Its cheap you can do it yourself.

No, neither the cold or hot air is coming out. So, I am wondering if it has anything to do with the new ignition switch I just install. Is this control by the ignition switch?
