Heater/AC went out yesterday

Corn Hauler
I have a Classic Auto Air system that I had installed last year. On the way home yesterday, it quit blowing (no fan sound). The heater does not work either. Anyone antiquated with this unit can give me a hand with trouble shooting? The shop that installed it did not give me any directions/manuals and now I think that shop is out of business.
 
Look on line for instructions of call the company. I believe there are 2 micro switches that could effect it. Could be simply the main fuse for the stock heater as that is the power source it uses. Does the compressor clutch engage in the A/C position?

I do not think so, how can I tell?
 
With the key in the run position, select the A/C for full cold. You should hear or see the compressor clutch click together. It is an electro-magnet. If nothing there, I would look at the main power supply.
 
Also iirc, there is a fuse on the blower itself inline really close to the blower motor hookup. Forgot to add I have the perfect fit system where the old heater box is replaced with the new unit.. You might do better to remove the dorky glove box thing they provided (if you have the same unit). You might be better able to see the fuse holder then.
 
Follow up - Fixed

The last fuse I put in was bad also. Replaced with a good fuse and now I have very cold AC.

Now to the next problem ...
 
whew, glad the AC is working! I will be happy to ride with you on the Power Tour, I have no AC!

What do you think Julie and Tera would think of you riding with me and the AC and them riding in yours without AC?
