Does not work from front or rear switch. Was working intermittently then stopped altogether. I have checked all conections and fuses. All fine.
SInce you indicated that it was working intermittently then quit working altogether the most likely culprit is probably a bad blower relay . The Contacts in a relay will sometimes burn and intermittently still conduct for while until they get so burnt that they won't conduct at all and the relay will have to be replaced. If you could get a Chilton Service Manual for the Vehicle in question it would probably show the exact location of the relay.
Testimonial: "Thank you. The relay was my next stop. I have had the dash apart already and checked all the connections on the control panel."
I ended up finding this valuable tip about a bad solder connection on the circuit board. I followed the instructions and it worked great!http://home.earthlink.net/~vqfaq/
