'94 Volvo 850 heater fan N/W speeds 1-3.

Hello,

My wagon has 113000 miles and suddenly the heater fan has stopped on speeds 1-3. It works fine on speed 4. Do you have any ideas or can you please provide the correct wiring diagram and I will do lots of head scratching.

Thanks,

On my 93 there are two fuses for the fan - one for speeds 1-3 and one for 4. Check your manual for the correct fuse,also the fuse panel is labeled. If it is not the fuse then it will be the fan resistor which is located next to the fan behind the glove box. You can find them online by searching for around 100 dollars. There are two types, one for auto air and one for manual, be sure you get the right one. Hope this helps, by the way there is a reasonable wiring diagram somewhere on this site, that's what I used to troubleshoot mine.
