dont think it has a fuse,if it is not working,it may be low on R134A or the low pressure switch is bad,is located on firewall on passenger side,also to charge the system the low pressure switch has to be removed,no big deal on this,it just screws in.


The problem is that there is no power going to the compressor, the system was build up to 80 lbs pressure, but the clutches would not click in. The lad that pressurized the system says it should click in above 10 lbs. Papa, do you believe the low pressure switch would prevent power going to the compressor? Thanks

then the low pressure switch is bad,also pressure should not be over 45lbs.,if it reads 80 on the guadge,it is way over charged,which will also cause it not to cut much pressure.
