I have a 2005 zd30 auto patrol.
The other day it wouldnt start. Not a battery problem as they are new.
Checked all the leads and they are all tight.

So sent it to nissan and they have told me its the air con pump needs replacing?
How is this stopping my car from starting?
If it is can i just disconnect it as i dont have a spare $1100 at the moment to replace the pump and belt that they say need replacing.
