2008 Kia Sedona – A/C stops working.

2008 Kia Sedona LX, A/C was working great, we stop, go into a store, come out and now the A/C does not work. Blowers still blow, and there have been no unusual noises from the engine compartment.

The 7.5A fuse was blown, so replaced, and on turning the A/C on it blows again.

Here is how I diagnosed and fixed it.

A/C was working fine
No mechanical noises
A/C suddenly ceases to work
A/C 7.5 fuse was blown
A/C fuse replaced, immediately blows the fuse
A/C relay checks out good
Removed A/C relay and measured from pin/socket 87 to ground, reads open-circuit
Removed old field coil, it measures between 1.4 and 1.7 ohms
New coil measured between 3.4 and 3.5 ohms
Disconnect battery
Removed under tray/splash shielding from underneath minivan
Removed pulley wheel from A/C compressor
Install new field coil
Re-assemble pulley etc
A/C now works

The correct part is Kia K97641-4D900 A/C Field Coil, cost $53.50 + tax from a Kia main dealer.
