If your relays are working, and you’ve determined your fan runs, then it’s one of two things: It’s either the resistor, or it’s low refrigerant. 126s are 30-40 years old at this point, so my money’s on your resistor. Not a complicated fix. I had my mechanic do it because my hands won’t fit down there, and I didn’t feel like messing around with moving the fuse box. He charged me $150. The resistor is about $35.
