Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
So the right fan does work and I assume since the left fan is not working the AC is not working well and the vehicle is overheating?
Here is the circuit diagram.
The first thing we need to see is if the PCM is even commanding the fan on. This can be done with a scan tool or by seeing if the PCM is grounding the fan control wires tested at the PCM connectors. If both fans are being commanded on but both are not running, let me know and we can diagnose the wiring and relays.

Hello again Chris here,
I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears your not pleased, or need more help.
Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.
