Hi. My car having a chemical/gas-like smell when entering the car before even start-up. This smells is worst during morning when first open car. Seems like no oil leak. Went to two workshop, they say most likely is cooling coil problem. Need to change the coil which cost quite ex. I abit not comvince as they only told me this solution by hearing my problem and smell. Cos i understand that for cooling coil, there's no way to check from exterior. So wondering is there anybody else having the same problem before or isit due to others problem? Before i proceed to replace the cooling coil which i dunno whether isit the cause of the problem. And I hd just change a new conpressor and filter a mths ago. Thanks.
