ridway Posted July 25, 2010 Report Posted July 25, 2010 Hi all, Had a burst hose on the high pressure side of the air con. This was caused by the rad fans not kicking in at idle due to a faulty 419 relay in the battery compartment. I found the pressure up to 550 psi on the air con manifold gauges - way to high for 134a. Anyway fault is fixed now and air con is working fine again, suction 40 psi liquid 145 psi and fans turning slowly when air con is switched on. Problem is it has left me with a flashing air con display on the central control which as we know indicates a fault or logged fault. Question is can this be cleared in any way without a laptop or star unit? I have heard that it may be possible to short out a couple of pins on the diagnostic port; is this true? Rich, Derbyshire
