What would make my aluminum air conditioning line that comes from the A/C radiator in the front to the firewall into the truck get extremely HOT

Asked by Bigreeser909 Jun 20, 2018 at 12:01 AM about the 2000 Dodge RAM 1500 SLT Quad Cab 4WD

Question type: General

I got a 2000 Dodge Ram 4x4 1500 5.2 and
it's been shutting off on me till it cools off
nobus has come up I've change the
computer crank sensor and Cam sensor
and relays and it's still shuts off but I
figured out that the  emergency shutdown
relay gets tripped but the other day I
noticed that the wires that plug into the
computer were real hot then today I
noticed that the air conditioning line that
goes right over the computer and wires
was extremely hot and I'm not using the
air conditioning because I noticed to a
while ago that if I run the air it shuts off
faster

If the a/c isn't on then the a/c lines aren't in use. However, they cannot get "hot" by design with the system hooked up correctly. Are you sure you're not feeling the heater lines instead? As far as the "no bus" light, that's something to do with your individual modules talking with each other. The most "descriptive" article on this subject is linked here. hopefully, your problem is easily found n repaired. Find a scanner that'll read codes or do the ignition off/on trick to retrieve them, that'll help you narrow your search. Good luck! http://batauto.com/threads/no-bus-code-on-99-dodge-ram-1500-laramie.14069/
