90 Camry Blower has a slide switch to adjust fan speed. I never had the lowest speed and I just lost the next speed up. I pulled the glove box and I think I found the resistor or relay, but I am not sure if there's a difference between a resistor or relay. After looking at ebay, I found a part that looked identical to the part i found, but it was called a relay. I also found a resistor part on ebay, which looks different. Fan still works in highest 2 speeds. Please advise.
