Im looking for any guidance possible on a most and only frustrating problem i have had with my 2000 crew cab frontier since it was new.
For most of this summer on speractic occasions the A/C blows hot air and the a/c clutch clearly is not engaged (green light is on) and of course its 100deg. outside -
when this occurs it seems to be in the hottest part of the day because
on mornings and nights A/C will blow cold upon startup and freeze you out of the cab.
even if it does blow hot air during the day - later and eventually it suddenly kicks in the clutch and cools fine until you turn the truck off at the store or something and startup again then it is hot air again and if your luck blow cold immed.
If I turned it off then on it would get cold again, sometimes!.
I took it to a local shop and they said the charge was fine and since when it does work it does freeze you out even when it is over 100 deg. outside here in Texas so i would think the charge is fine. another shop wanted to replace everything and I was sceptical of this since it would be cold when it worked. They wanted to replace everything....
I did myself as a shot in the dark replace the a/c relay on the engine compartment with a brand new relay from nissan but no luck!
I did find a thread from some other nissan forum that talked about replacing the A/C "thermistor" and if anyone has knowledge of replacing the "thermistor" i would throw money at that part in hopes of fixing this problem.
thanks in advance for any ideals!
