south Texas , York Rife Freemason | i havent any experence with a FLD ,but any system in a mobile application (that i have seen annyway) has an orfice tube like a GM has or an expansion valve .the century trucks we have have an expansion valve in the sleeper along with a blower motor ,evap ., h. core ect . basically 2 seperate systems running off a "T" at the firewall ,from the compressor . about the only way you can figure out much at this point is with some gages ,im guessing the refigerant leaked out . in the case of a leak a "sniffer" and some floresent dye can help you find the leaks . your friend should have the necassary tools and know-how to fix it . ALOT of a truck mechanics job is a/c work this time of year. |
