HVAC blower Failure on 94 B'ville
I have a 94 B'vile w/114,000 miles. Last night the a/c fan went out. Regardless of mode (a/c, vent, defrost, heat, etc.), the fan will not blow at any speed or any switch position. Is this likely the fan motor itself dying or is there a circuit breaker or fan relay that might be at fault and if so how could I easily diagnose to see if it'* fan motor or something else? I've checked the fue panel under left side of dash and tapped on relays under big black cover in engine compartment. I removed dash and looked at switch to see if I saw a loose wire but all looks OK.
I don't have a wiring diagram. Anything else I'm missing.
please email me with ideas at mikemore@rocketmail.com
Engine is 3.8L V6 (non-supercharged)
Thanks,
Mike

You more than likely need a Blower control Module which is located under the fuse relay center on the firewall. It'* about 60-70 bucks from GM. PN 12368389.
