IS 200t, both the fan and the ac stopped working. Everything else is working fine. My mechanic cannot see it till Friday.
Any quick fix I could try?

 

I haven't been able to figure out the verbal command to turn the AC off an on either. AC compressor that is. The car always detects "AC" as climate control so it will just turn the fan off or on like you said.

I turn the AC compressor off in the winter unless it's especially humid and it's needed to reduce condensation on the inside of the windows. Supposedly it saves a bit on MPG's though I've never compared any long term differences.

 

Did you check the fuses?

 

Try disconnecting the -ve from the main battery for 10 mins and reconnecting it.

 

+1 Check fuses. Best place to start.
