Question about 1993 Volvo 850

My 1993 Volvo 850 has a a/c blower fan that will not come on. The ECU has no codes stored 1-1-1. The a/c compressor comes on and runs. Any ideas, just no fan

    My son just purchased the same car - no blower fan and the fuse is ok.

    the fan stopped working for a long time. recently, it started working again but only when you turn on the engine, and stops working afterwards. seems to me that there is some electrical problem.

I had the same issue so I took the glove box and kick panel off to gain access to the blower motor. I then actuated the fan selector switch and could hear the sound of the motor trying to start up but it couldnt seem to get going and then the sound would just stop after about a second. So i gave it a couple of taps with a rubber mallet. It started spinning almost instantly. I then removed the motor from the shroud to see what was wrong with it. I noticed that there was a lot of build up on the blades as well as on the armature so I cleaned everything up as best I could, making sure to clean the contacts as well. Finally I inspected the inside of the shroud and noticed that the reason the fan couldnt spin at first is because the blades were hitting the inside of the shroud. So I sanded down the fan blades as well as the inside edge of the inner shroud. I reassembled the unit and it has been working perfect ever since.  I was expecting that the relay was bad or the motor and it turned out to be a free fix. Hope this helps.

Where is the heater fan relay on a Volvo 1994 850?

The blower motor relay is behind the glove box. If your blower only runs on high it's the resistor and it's behind the glove box too.

No a/c on my volvo 93 850

Blower motor or engine light won't affect the A/C compressor. Locate the compressor under the hood and with engine running have someone turn the A/C on and off. You should be sble to hear it engage and disengage. If it does not, Ck your fuses, If all is good, I have to recommend anA/C Technician because there are a few other items that could be of issue requiring special equipment. Good Luck- Ned-

Code stereo volvo 1993 850 GLT

If you need the security code, you need to call a Volvo dealer and give them the VIN number, provided it is the same stereo the car came with.  Most dealers will do it for free, if you can't find one, call Boston Volvo Village.

1993 volvo 850 heater blower works sometime tell me why?

These models had problems with the blower motor power stage, which is what controls the fan speed, and the blower motors wear out. There a good chance it needs both!
