A/C and fan problems
Hi all,
I started having some issues 2 days ago in my 2013 G63. Radiator fan goes on high about 30 seconds/1 min after turning the car on and just stays on high. Mind you its about 60 degrees outside. Also A/C does not blow cold anymore.
Everything was working fine last week when I dropped the car off to have minor body work done. Two days ago, I received the car back and the issue was there
Heres what Ive checked:
Coolant level is ok
A/C pressure sensor is replaced
Battery was replaced
All relays in the passenger front fuse box replaced
All fuses seem to be working properly
Temp gage shows about 90/95 degrees constantly, it does not increase
Any help is appreciated,
TIA

You need to hook a scanner up and find out what is triggering the fan to come on. Fan needs speed signal from M.E. or it will default to full hi but need a scope to properly check what M.E. is requesting.

thanks for everyones reply. for anyone wondering, this ended up being a burned fuse in the fuse box in the engine bay passenger side. The fuse box does not look like a fuse box at all and has very strange fuses inside of it. one of those fuses were burnt. its not possible to find individual fuse so had to replace the whole box. again very strange
