So I asked a question about the ac blowing hot and cold randomly on my truck and I looked at it today and put my hand on the accumulator/drier and it was about as cold as a can of coke, maybe a little warmer. the two lines coming out of it were even colder like 40 degrees. Now their was another long line that went from the firewall over to the fender well and it looked like it was painted white, but it turned out it was actually ice!
Any ideas on what's going on? Is it low on Freon? I did have them replace everything but the condenser and the evaporator core.
