2003 Mini Cooler 1.6l
It has two problems an they may be related.
1. When the engine is cold and the car is started, the high speed fan comes on after 5 seconds and runs as long as the engine is on. Temperature gauge works and reads at midpoint. The ECU is clearly turning the fan on 5 sec after the engine is started even when the engine is cold. Fan relay is OK. ( I did not check infamous low speed resistor)
2. AC compressor does not kick on when AC switch is activated. Blue snowflake light illuminates on console but no compressor. AC charge is ok (checked with gages). AC relay has power and compressor comes on and air gets cold when I jumper the contacts at the relay socket.
Tried resetting ECU to no effect.
Thanks for any help
What makes this problem better or worse?
problem is constant
How long has your 2003 Mini Cooper had this problem?
Bought the car over the winter with bad transmission. I replaced the transmission with no issues, Was told AC worked last summer and High speed fan did not come on.
RepairPal Certified shops can diagnose and repair your 2003 Mini Cooper. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
First stage fuse and relay - you do the testing in any manner that’s comfortable for you.
I always TEST each and every fuse I can find on the vehicle anytime an electrical problem is present - using a 12 volt test light - with key on.
You’ll need a diagnostic flow chart and a wiring schematic for further testing.

Good luck with it!
Pushrod,
I will double check all (Fan and AC) associated fuses for continuity. I only checked the AC. I wouldn't think the fan would come on if the fuse was blown but anything is possible now days
thanks
Relay circuits are protected by fuse.
