black jack Posted May 7, 2023 Share Posted May 7, 2023 Went to get new springs fitted , battery was flat on car so popped down in my other A3 and borrowed there jump pack. When i got the car back with new springs fitted and new battery the heater blower was not working ? it had been working up to then. i do tend to leave the heater on , would the booster pack have blown some thing. i have replaced the blower with a complete unit and the heater controls , all the fuses are good and worm air does come through the vents,its like the the blower is not getting a signal. PLEASE HELP AS ITS DOING MY HEAD IN ? Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted May 7, 2023 Share Posted May 7, 2023 New batteries have to be coded to the car to get full functionality of all the electrical systems. Was that done? 1 Quote Link to comment Share on other sites More sharing options...

So at a bit of a loss. Will have to try something else 😕 Quote Link to comment Share on other sites More sharing options...
