Last night I was sound asleep and my Disco alarm started going off. I went outside and the blowers n the radiator were randomly turning on and off. That was triggering the alarm. I sat in it for a few minutes and listened and it sounds like a relay of some sort was clicking on the passenger side behind the panel at the foot well. I have starting having issues with those blowers sometimes when I run the a/c, and i turn the truck off with the a/c on, the blowers will stay on. Anyone have any ideas? Simple fix i hope!

 

does anyone have any ideas about this condenser fan issue?

 

The condensor fans will continue to run after you shut the engine off if the engine is to hot.
These fans are supposed to come on/stay on in a overheat/run to hot situation weather or not you use the a/c.
Keep in mind that the a/c dumps alot of heat into the radiator and makes the engine run hotter.
Now with that being said, and the fans coming on in the middle of the night when the engine is cold tells me that you most likly have a bad sending unit for these fans.
It is reading to hot even though the engine is cold and then turing the fans on.
You can unplug the fans until you get a new sending unit.

You can double check the engine temp buy using a OBDII scanner that reads engine temps, plug it in and moniter the engine temp while you drive.

 

Why not try AC auto condenser? Even as a kid, cars and trucks have always been my fancy. When my family acquired a GMC truck for our farm in my early 20's I eagerly took charge of its maintenance and repair needs from simple auto lights replacement to handling AC condenser matters.
