EBD/ABS Failure light on, air-con then not working
My 159 Q4 3.2 has the warning light of ABS and EBD on sometimes, and then the air-con is not working after when the lights are on, the air-con pump doesnt work then.
It did happen before but I couldn't find out the problem, then I changed a new battery and the battery terminal. The problems solved for a month ( the warning light didnt come out for a month) but now it happen again, around 2-3 times a week. Its really annoying as it is very hot and humid in Hong kong now.....
and the weird thing is when the ABS/EBD lights are on, the air con is not working, ( the pump is not running) , but if I kept the rpm higher, around 4-5000, the air con pump will run sometimes but on and off....
anyone has same experience or advice? much appreciate
