About a month ago I was tried turning on my heater in my 1988 FJ62. It did not work. As I accelerated on the highway, I noticed that the air coming into the car was warm. I also tested out the cold. It also worked but would not blow in any of the positions between low and high. I moved the lever between fresh air and recirculating a few times and all of a sudden the blower kicked back on. This is beginning to happen more often and my current fix is to move the fresh air/ recirculating air lever back and forth until the blower kicks back on. Has anyone had this issue and what was the fix? I would like to get it fixed before it goes out in the middle of summer. Thank you.
