So cold season is approaching...
I turn the temp **** to the hot side, and I start getting a fuel smell coming from the vents...
A/C is not on, and when it is on the smell is stronger.
If the temp **** is set to cold side there's no smell.

Anyone can point me in the right direction for a solution?

A/C on/off Temp **** Cold side = No smell
A/C on/off Temp **** Hot side = Fuel smell

EVAP canister has been overflowed. It supposedly never dries, but after a year or so it might stop smelling so bad if you don't overfill your tank again.

So you're saying I over filled my tank and it overflowed the EVAP canister? - Cause this would make sense, I might have over filled gas tank when I wanted to add some fuel system cleaner additive, which I filled tank for.

Sure it's not antifreeze you're smelling? Evap system shouldn't have anything to do with your problem.

Happens to many people. The EVAP purges back if gas is overfilled and it will smell for a LOOONNNGGG time when it gets warm.

Got into an SC at a dealership that had this problem. Dealership keep saying they thought prior owner had a gas can tip over in the back and saturate the carpet. So there was no trunk carpet in this car. Then I told the guy about the evap can and that's probably what it was. Guy was like "Doh "

Car had a million and six miles on it anyway.

How does the smell from the evap can get into the system? I thought their was a seperate canister for AC evap. Sure its not coolant from your heater core? I dont think that Lexus (could be wrong) would connect the Fuel system to the heater system. I mean Gas vapor from fuel hitting the hot heater core.........

Not sure but like I mentioned earlier, I only get the gas smell when I turn the Temp **** to the heat side. If I keep it on the cold side there's no smell.
