A/C fans not working

These issues may be related but I suspect they are not. Let's tackle the fans not coming on and then we can start a new post for the A/C not blowing cold if it doesn't correct it as well.

Take a look at this wiring diagram when you say relay 2 doesn't work, where do you have power and where do you not? The PCM grounds relay number 1 and number 2 in order to get relay number 3 to be grounded and turn on the left fan.

So we just need to find out where we have power and where we do not. If the number 2 relay is not working have you swapped it out?

So you jumped power directly to the fan and the right one didn't work?

Then when you check power at relay 2 you have no power from the fuse or the PCM? Take a look at the wiring diagram and tell me where you have no power. Which terminal of the relay?

The relay 2 is the high speed relay so both fans are run off of relay 1 on low speed and 2 on high speed. So we just need to start narrowing down which terminal we we don't have power.

I am starting to think we have an issue with the PCM but we need more info to confirm this. Let me know and we can go from there. Thanks
