'94 JGC unusual AC problem
Iíve been reading about problems with the AC fan working only on high, but have yet to find a descripton of the problem Iím now having on my 94 JC Laredo, 5.2: when I start the car, the AC fan works fine, on all speeds. But on a long drive, after about 45 minutes, the output from the vents begins to decrease, and finally ceases. The FAN never stops, but the output to the vents is blocked . . . and not just to the AC vents, but to the floor vents and the defroster as well. If I turn off the AC completely, wait about 10 minutes, and turn it back on, I again have fully functional air - - but now the gradual shut-off happens faster.
Again, the fan never stops, but the output does! And this is the case on all fan speeds.
I was thinking about trying to change the blower resistor, but that doesnít sound like it will solve this problem.
Thanks in advance for any help!
