1999 986 Left Radiator Fan Not Working

[Vidyashankara]

Also my blower motor went out abruptly this morning. I get no air from my vents. Fuses are good. How do I troubleshoot this?

The heater/AC relay is number 18. The fan relays are 19, 20, 21 and 22.
You probably moved a bad relay into socket 18 or are confused about which relay is which and have #18 pulled.

That’s weird. I don’t have any relay at 18. Never did... I have 19,20,21 and 22

This is so weird. I moved one of the relays from 19 to 18 and the blower motor works now. I moved one from 20 to 19, and the low speed fan still doesn’t work.

I need to buy an extra relay for 18. I don’t know how the AC worked all these months without a relay in 18 🤷🏽****♂️ i took a pic of the relays many weeks ago and it isn’t there on 18 then too...

How do I troubleshoot whether I have a resistor problem or a wiring issue?

Sorry, no idea what I was smoking last weekend. There were 5 relays and i lost one when i moving the relays around...

The low speed fan still isn't running. Shorting 30 and 87 did not do get the fans running and the resistor and the fan is brand new. How would I troubleshoot a wiring problem? Attached pics of the resistor.

When I had the stereo system and rear view camera installed, they have the camera wiring a bit weird and the wires were pulled apart when i used the convertible top. they fixed it when I took back. I wonder if something happened then.
