Need A/C Help for 03 Suburban (in Kansas Heat)
A/C worked in March, stopped in April.
Mechanic replaced ambient sensor, said I had plenty of refrigerant, but the a/c clutch was probably bad - $1300.
I replaced the clutch/coil and it worked for 30 minutes, but I hadn't properly secured the snap ring - the coil spun and fried. I replaced the clutch/coil again; it worked for 3 minutes and stopped - blown fuse. Fuse doesn't blow if compressor is disconnected. Replaced wiring connector - fuse still blows. Jumped the 87/30 terminals in the fuse box, clutch clicked and blew the fuse. Checked coil with multimeter and got less than 1 ohm. Is the coil bad and I need to replace it, or is it the compressor?
Thanks for any guidance.
