97 1500 360. When I turn on the ac, the fan in the cab runs no problem but the pump dosn't engage. Not sure if its a fuse, dont know it there is a fuse for it. Im pretty sure its not that the clutch is engaged because it dosnt spin at all.

If anyone has any ideas let me know.

Thanks

 

It probably has no r134a in it. There is most likely a leak. The compressor will not run if it's low or empty.

 

well if there happens to be a leak is there any way i can find it and stop it before i go and waste 60.00 to re fill it?

 

you can try some Red Angel A/C stop leak. If that doesn't seal it, then you have bigger problems.

 

Take it to an AC shop, they more than likely will diagnose for free. You can also get a can of 134a with the UV in it. But I suspect it's the evap core that's leaking.
