DocWC Posted April 30, 2019 Share Posted April 30, 2019 Any of you guys having constant problems out of your LRU model air conditioning constantly? I've got 11 of these things, and just when I finally figured out how to re-engineer all the issues I was having on the early models, I got a handful of 2018's and they give me a headache constantly. It's a piss poor engineering design to begin with, but I've got trucks that literally EVERY component checks out on, and they still freeze up, or they suck too much condensation through the module and plug everything up, and the list goes on, and on. What are some of the things you've found wrong with them? I've got two of these 18 models that are giving me the blues right now. Freeze switches are good, charge is on the money, heater valves are closed (to isolate the electronic actuators from opening up the heat on their own.....yea, had 2 of them do that already), evaporators clean, pressures on the money when idle/high idle.....they'll take off down the road and an hour later they're froze up.
