A blinking light shows a fault with the air conditioning system. Does the system cool sufficiently? The fault could be an electrical glitch or a sign off a pressure problem.
Yes it cools but I do smell antifreeze ocassionally. I've read manual but it doens't mention anything on this.
Thanks for your response
