A week ago my aircon started blowing hot air, compressor clicks on etc Low pressure pipe is hot and high pressure pipe is cold..ac bloke said its definitely the evaporator under the dash and I'm looking at $1000 to get it fixed. is this a commen problem with 2004 camry altise? it was working perfectly until last week, unsure if I should get the evap replaced\fixed or just refill the gas and check for leaks
