***'94 GTS HVAC Blower Not working***
Got this 1994 GTS (27K miles) with a HVAC fan not working on any speed. Fuse is clean with no heat related melting evidence. I've switched out relays for the blower, defrost, relay X with known good relays, no joy. I did jump the blower relay terminals (30 & 87) and the blower works on all speeds and the A/C compressor kicks on as well as the radiator fans. No voltage on terminal 86 to trigger the relay. What is the next step? Maybe pulling the head unit?

Turn the fan to the full on position or the defrost position and see if that gives you fan speed. I suspect your blower resistor pack is probably in need of cleaning. Pull it and spray is down it DioxIT. Search for Magic blower syndrom

Guys,
Issue solved. Fuse #37 bad contact in the fuse socket. Some manipulation of the contacts and Deoxit seems to have done the trick. #37 definitely triggers the relays.
Thanks guys!
