Evaporator Mold??

My truck has recently developed a musky smell in the A/C. I think this is prolly mold on the evaporator core?

My question is, , , can I fix this issue myself or is this something for the dealership? Has anyone had this condition and been able to home remedy the problem. How did you do it?

I live in the desert so humidity is very low but I know the evaporator drain works as we have been having the monsoons lately and I see puddles under the truck when I stop.

I had the same problem on one of my past trucks. I tried to fix it myself to no avail. I ended up going to the dealership who not only cleaned it with a foam that filled the HVAC system, but also put an add on unit on the truck (under warranty) that caused the blower fan to run for 2 minutes after shut down drying up the evaporator. It worked well and I never had a problem after that. I wish I kept the part numbers for the unit but the dealer should know what it is if you elect to go that route.
FWIW, before the repair was finally done, they told me not to use "Max A/C" as that was part of the problem.

It might help, before you shut down the truck, is to cut the A/C off and let the fan run till the air flow is warm again. Usually only takes 30 - 60 seconds. Works for me and no molded up evaporator or smell. If it's already molded up most likely will have to have it cleaned first.
