Burning smell from air con pump

hi guys can anyone help me with this one?

 

i took her out today and with in minites i had a strong burning smell like rubber or electical suddenly smoke started pouring out the bonnet and i pooped it!

 

under the bonnet it looked like it was coming from the aircon pump. there seems to be a rubber seal on the inside which has just tried to melt away! any ideas what this could be?

 

Thanks

Air con pump bearing collapsed maybe? Possibly resulting in the seal being excessively rubbed?

 

Just a guess. When you say 'it sounds rattly', is there play in the air con pulley if you shake it by hand? Try removing the belt and turn the air con pulley - also check the aux belt in case the air con pump has seized completely and caused the belt to heat up causing the smoke

ok cool i will have a look, it seems to be when the mag clutch is engaging, i know this sounds silly but could you not just unplug it so it does not get any signal from the ecu? there for just acting as just a pulley?

?

 

Just turn your air con to off.
