c5 2000 hvac fan
Gentlemen my friend has a 2000 vert and she said hvac fan quit blowing. I looked at my OM for 2001 and fuse box in footwell indicated fuse 27 is for hvac controls and 51 is for the fan motor. I guess 27 could control the fan switch that controls the fan motor not sure, just asking. Thanks

Sorry U R correct # 51 is not a relay but a maxi fuse. I will take a look at these fuses when she brings the vette buy in a few days. Would U think it is one of the mini fuses or the maxi fuse 51, I know that is hard to tell knowing no more than we know at present. I think it is probably the dual zone but not 100%. Would fuse 18 and 27 control the motor or only 51? Thanks man

More complex than just fuses if it is dual climate control. The speed of the fan is controlled by a control module and if the control module has failed the fan will not run even if the fuse is good.
On the manual system there is a resistor pack that controls the speed. That pack is known to burn out. BUT, if the pack is bad the fan (manual system) will still run in high speed because the resistor pack is bypassed for high speed.
Need to know which type it is to offer more help. Dual zone or manual???
