When I turn on the A/C, there is strange smell.
I plan to flush my 98 camry evaporator. I find it difficult.
Anyone could give me some advice?

thanks a lot!

[QUOTE=stanleyeye]When I turn on the A/C, there is strange smell.

Most likely mold in the air chambers.
Simplest cure I've heard is to open the windows and run heater at high temp. for about five minutes. High heat will kill the growth causing the odor.
Then, to prevent recurrence, turn off A/C a few miles before parking (but drive with the fan on, and recirculate off - that is, outside air coming in) to help clear moisture from the vents before shutting down.
