Dead HEVAC or bad connections. Diagnostics might help.

thanks for the reply data tech - I have a spare hevac unit, If I swap it will it need to go on the diagnostics to recognise the new one and clear any faults it has logged

plug and play straight swap,any fault codes logged will need to be cleared but it will still work

thanks for the advice gents - swapped it for spare unit - appears O.K. apart form the hand book symbol- which I already know is due to the compressor clutch being U/S

thanks again
