I have a 90 Mazda B2600i Extended Cab LE5 Manual transmisison truck, that has served me well over 180,000 miles so far. The probelm I have now, is that the Air conditioning no longer functions by the button. I.E. When I turn the truck on, push the AC button in, turn on the system, I do not get cold air.
I troubleshot the system to the best of my ability, and found that the system is full of freon, and cools wonderfully when I bypass the wire, and connect a hot power to the single wire that goes to the AC Clutch compressor unit. This tells me that for some reason my AC clutch is not being given power, to turn on. I think it may be the AC relay, however, I have no clue as to where this is, nor does the local dealer, or anyone else online that i've been able to find.
The AC button, should light up green when active, and it does not. The AC fuse is good, as well.
Any and all help is greatly appreciated, as today it hit a record high of 104* with a heat index of 114* here in Columbia, SC.
have the same problem?
