I have replaced the fan switch only to find out it has no power to it. The relays have been replaced although it was some time ago. Could buy three new relays but I don't think that is the problem. The fuse link that my book mentioned did not say were to find them or it. In the meantime, I have no cooling. The air is not working as well, in fact the blower fan inside the car is not working. Checked all fuses and none are broken. What am I missing?
