The Volvo's use an ignition switch that feeds power directly to the accessories. Probably wear is causing an intermittent connection. We own 3 Volvo cars right now, and all 3 have had the same issue. For the 740's, it's a pain in the butt to replace. The 850 is a 15 minute job. Pull the black plastic bezel from under the steering wheel, 4 Torx T-15 screws, and switch is right there. Switch is $60-$75 depending where you find it. FCPGroton or IPD are your best bet. Good Luck- PRM
The intermittent functioning of the heater blower in a 1993 Volvo 850 could be due to a few common issues. It may be caused by a faulty blower motor resistor, which controls the speed of the blower, or a failing blower motor itself. Additionally, issues with the electrical connections, such as corroded wires or a bad relay, can also lead to inconsistent operation. Checking these components can help diagnose and resolve the problem.
In the HVAC compartment attached to the firewall on the right side of the vehicle.
In a 2003 Volvo V40, the heater blower unit is typically located under the dashboard on the passenger side of the vehicle. To access it, you may need to remove the lower dashboard panel and possibly the glove compartment. The blower motor itself is mounted to the heater assembly, which is connected to the vehicle's climate control system. If you're troubleshooting or replacing it, ensure the vehicle is turned off and disconnected from power for safety.
In a Volvo S40, the blower motor is typically located under the dashboard on the passenger side. To access it, you may need to remove the lower dashboard panel and possibly the glove compartment. The blower motor is usually mounted in the heater housing and can be identified by its cylindrical shape and electrical connector.
1 engine cooling fan and 1 heater/ac blower fan
Up under dash, passenger side. My mechanic described it as "take a blower, build a Volvo around it". I paid abt $800 several years ago at a non-dealer Volvo shop. Process starts with taking inside of glove box out - you can see it from there...
Answer 1. blown fuse 2. broken wire 3. broken heat sensor (on side of heater housing, inside car) 4. burnt wires 4. bad blower motor speed resistor 5. bad blower motor 6. bad blower motor switch
Yes, but your Volvo will have very little power without the turbo.
The fuse should be under the hood in the fuse panel it is #32 on the 97 850 sedan. blower speed 4 is on a separate fuse. I had the problem of speeds 1,2,3 not working and the culprit was the balast resistor. it is ceramic unlike the metal coils used in the American cars. the ceramic deteriorates and the wires break inside the resistor. see answer for ......Where is the air and heater blower relay located on a Volvo 850?.... to find out where the resistor is located.
The diesel turbo can only fit on a Volvo 850 with a little fabrication.
yes
were is the camshaft position sensor on 1999 Volvo s80 turbo
