All,
1990, HDJ81, 1-HDT.
While driving this morning to a favorite local MTB trail, the following happened…..
1) highway speeds, windows up, AC on.
2) AC seemed to NOT be putting out the normal temperature air. It was warm (85F) so i chocked it up to the temp outside. It is afaik the original system.
3) A mild (electrical?) smell was noticed coming through the vents.
4) Sudden loss of airflow with ALL gauges except Fuel and Speedometer showing zero.
5) NO warning lights at all.
6) All lights continued to work, turn signals, head lights etc…
7) Clock and Stereo continue to work.
8) Smell of something continued and intensified.
At first I thought alternator, but NO lights indicating. I was off the highway on a side road so I pulled over to take a peek under the hood.
NO belts twisted or missing, I didnt hear any squealing or strange noises.
I thought possibly a fusible link had blown but wasnt sure.
I turned my truck around and headed home. NO strange noises or vibrations were heard on the 20 min drive back at highway speeds.
I wasnt sure if i could shut the engine down or start it again so i pulled all the way into my garage. The engine did shut down normally. I did NOT attempt a restart.
After clearing some space in the garage, i grabbed some light, popped the hood and here is what i found……
Clearly the AC compressor may have a bearing or seal issue. There is black lube as indicated in the pictures.
Why would the gauges that I indicated above suddenly die yet other gauges continued to work?
Are there multiple issues going on?
I havent checked any of the fusible links, the alternator belt is tight.
Is there some sort of electrical issue going on in addition to the obvious AC compressor throwing lube?
Thank you for any ideas/thoughts/questions.
