85 740 with manual climate control and a/c. Been through the entire FAQs. Blower stopped working. Tried on position 5, thought I heard the blower trying to run. Replaced resistor. With glove box off, tried position 5 again. This time I heard a relay trying to click. Behind the glove box are two relays, a standard bosch type and an odd rectangulor relay. Put 12vlts to the blower, it works, replaced both relays, same sound. Guessing its in the switch. Can the switch by itself be replaced or do I need a whole manual climate control assembly?
