blower motor confusion

[marz442]

I checked the wires and the red wire had power going to it. I here the relay click but no high speed
I just lost any other Ideas?

red wire should have battery voltage to it at all times. in high speed position purple wire coming out of relay should have battery voltage. clicking relay does not make it good as contact inside relay could be bad/ corroded. voltage measurements should be taken at relay connector.

It may be the blower switch. I changed mine recently and got it at Napa The red feed wire got burnt by the headers and shorted out the system. It fried the resister and switch

Im starting to give up, I tried a new switch, new resistor , and new blower and nothing is working.

then start from then switch and test the wiring of the whole system

Have any pics of the conector by the valve cover, or what im to be looking for? I just gave it another try and nothing no high. If any one has any pics of what I should be looking for as far as the conector by the valve cover please post it.

just follow the red 10 gauge wire from the relay to the front right side of the engine and you'll find the black connector. If the fan is working in the low and med speeds then I put my money on the red wire having a bad connection at that connector...

any luck finding the problem yet?
