Using a wire diagram for a '70 Corvette, check continuity between wire terminations. It's most likely a bad connection somewhere, be it a wire or a terminal. Hope that helps!-ku2002
right side firewall under right fender
No air flow from the heater duct of an 88 Chevrolet Corvette is often caused by a defective blower motor. A blocked air inlet or defective switch can also cause this issue.
For a car as old as a 1985 model, it could be that the heater blower motor control module has gone out. A new one for a 1985 Corvette is around $165 to $175 at auto parts stores.
yes, the fan bearing is worn out
Bad blower motor? Blown blower motor fuse? Bad fan switch? Bad blower resistor pack?
Well -- I found out that the heater blower is located under the hood against the firewall right above the windshield washer fluid container. You will need to remove the panel in front of it, then remove the blower and shroud, and R & R. The blower replacement was fairly inexpensive -- MUCH less at NAPA than at a dealer.
Remove the wiring harness from the back of your 2005 Chevy Cavalier heater blower motor. Remove the heater blower motor retaining bolts. Remove the heater blower fan.
if the blower motor still works, somebody probably bypassed the heater core in the past.
Heater blower resistor is what controls the low medium high speeds...
The blower may simply have burned out. If the blower is out then the heater probably still works.
Remove the wiring harness to the heater blower fan. Remove the retaining bolts. Remove the fan from the blower. Reverse the process to install the new heater blower fan.
try wiggling the wires at the blower resistor if don't work then tap on blower motor
