A problem exists.
Person 1 perceives the problem. Based on whatever knowledge they may or may not have. They store that understanding (correct or incorrect) in their mind. They use their communications skills (good or bad) to relay a simplified and less than complete version of that perception of the problem from their memory to person 2
Person 2 interprets the communication based on their knowledge and experience (or lack thereof). More chance for distortions as they then store that information in their mind. Eventually they pull that information out of their memory and relay an inescapably changed version of what they received to person 3. Communication is once again needed and there is again, the opportunity for distortion of the original perception of whatever event transpired.
Person 3 interprets the communication based on their knowledge and experience (or lack thereof). More chance for distortions as they then store that information in their mind. Eventually they pull that information out of their memory and relay a new version of it to others via the words that they type onto the screen.
Lots and lots of people read the words and form perceptions in their minds... based on their knowledge and experience (or lack thereof) and memories. And everyone starts guessing and the games begin.
My point? My point is that without detailed, accurate and knowledgeable first hand observations from a source which has a decent understanding of the symptoms of the problem and all of the systems that might or might not be creating it AND accurate communications to relay the perceptions of the problem even the most skilled and knowledgeable person can do little more than guess.
There are folks in this forum who could absolutely solve this problem if it was in their hands. Some of us could very likely look the rig over and say "yep, seen this a few times, and... yep, there ya go... fixed it." With more detailed and confirmed accurate info, it would not be unreasonable or unusual to diagnose and even explain what needs to be done right here over the net. But with minimal information, being relayed through three different persons... It is heading toward unreasonable and unusual territory.
It is highly unlikely that any of us can tell you what the problem is based on the information at hand.. Especially since you do not own the vehicle and can not "try this and then try that" and factor in any feedback from the net as you tinker in your garage. More than likely the actual problem could be tossed out to you. Mixed in with a LOT of wrong answers.
If you buy this rig, in this condition, don't pay top dollar. (I would NEVER sell a vehicle in this state myself. The seller is always gonna loose money in a situation like this. I have, more than once, purchased a rig for at/under $1000 and after an hour and a $100 part had a $10,000 rig in my hands.)
It is doubtful that it is an expensive fix. It is doubtful that it is an overly complicated fix for someone who is skilled, knowledgeable and experienced with this rig and it's systems. But you are either going to need to find that someone who is close to you or you are gonna have to start the journey to become that someone.
It is a fun path to follow though.
