heater blowing fuses

[ebd12694]

I have a 1980 camaro.ac and heat car.. i wired everything up like the diagram shows and now when i turn on the blower motor only the two middle switches power the blower on and when it comes on its only high....then after a while it will blow the fuse....what is causing this? i cant figure this out...

Did you replace the blower resistor yet?

 

[ebd12694]

no i cant find one but it was working before i rewired so i dnt think thats the problem but i at ends meet

are you trying to power the blower motor on high with the fuse or do you have the wire from the blower relay going directly to the battery?

 

[ebd12694]

i have a constant battery wire going to the relay from the fuse block....which is what powers the motor when u turn it to high.... but i also have the relay wired like the diagram on here showed so that the middle and low powers work also but so far that hasnt been working out
