97 Discovery 1 A.c. dont run also also both cooling fans dont turn on when putting on defrost. Also when you push in button to turn on air light on switch doesnt come on. I checked fuses all check ok and also jumped ac clutch with 12 volts and clutch plate ran and started blowing cold air. Any suggestions what to go a after next will be appreciated.

 

If the fuses are ok .... clean/check the connections to compressor , fans ,

( are you referring to the clutch plate in the compressor ? )

 

yes clutch plate is not turning unless I hot wire plug

 

could be low on refrigerant, some vehicles will not run the AC if the outside temp is below a certain temp.

 

Find the low pressure switch for the system and jump it out. if everything works its low On gas

 

Be sure to get the system checked for leaks , if its that ? or else it will be back to square one after a while ...

also check compressor oil ..

 

Dash button can go bad, if you end up being low on r134a and have rear a/c, the metal line in drivers rear wheel well goes bad, rots through
