I have a 1994 Volvo 940 with 4 cyclinder engine (no turbo) with auto transmission.
For the last years or so, the electric fan blower virtually stops when I accelerate the car. Actually the harder I accelerate, the slower the fan blows. That is when I just have the fan on, or heater or air-conditioning. But, as soon as I leave my foot off the gas padel, the fan will blow strong again.
All other electrical equipment seems to work. Can you tell me what is the problem? Thank you.
