Volvo S90

If your Volvo S90 won't shift into park from drive, it could be due to a few common issues. One possibility is a malfunctioning brake light switch, which prevents the gear shift from moving out of drive when the brake pedal isn't engaged. Additionally, low transmission fluid or a problem with the transmission itself may also cause shifting issues. It's advisable to consult a professional mechanic or your local dealership for a thorough diagnosis.

On a 1998 Volvo S90, the flasher relay switch is typically located in the fuse box, which is found under the dashboard on the driver's side. You may need to remove a cover or access panel to reach it. The relay itself is usually a small, rectangular component that can be identified by its markings or by consulting the vehicle's manual for specific details.

To replace the brake booster on a 1997 Volvo S90, start by disconnecting the negative battery cable and removing the brake master cylinder from the booster. Next, detach the vacuum hose and any other connections to the brake booster. Remove the mounting bolts securing the booster to the firewall, then carefully pull it out from the engine compartment. Install the new booster by reversing the removal steps, ensuring all connections are secure before reattaching the master cylinder and reconnecting the battery.

To disarm the alarm on a Volvo S90, simply unlock the vehicle using the key fob or the physical key. If the alarm is triggered, it will stop once you unlock the doors. Additionally, you can disarm the alarm by starting the engine with the key fob inside the vehicle. If the alarm continues to sound, check the owner's manual for specific troubleshooting steps.

Labor costs for replacing a radiator in a 1998 Volvo S90 typically range from $100 to $150 per hour, depending on the shop's location and expertise. The job may take around 2 to 4 hours, leading to a total labor cost of approximately $200 to $600. Additional costs for parts and coolant may also apply, so it's best to get a detailed quote from a mechanic for the total estimate.

If your 1998 Volvo S90 won't shift into park and does not start in neutral, it may indicate an issue with the shift interlock system or the transmission linkage. Check for any obstructions or damage to the gear selector mechanism. Additionally, ensure that the brake pedal is fully depressed when trying to shift gears, as this can affect the interlock system. If the problem persists, consider consulting a mechanic for further diagnosis.

To reset the airbag service light on a 1999 Volvo S80, first, ensure the ignition is off. Then, turn the ignition key to the "On" position without starting the engine. Press and hold the airbag reset button, typically located under the dashboard or near the driver's side, for about 10 seconds until the light turns off. Finally, turn off the ignition and start the vehicle to check if the light remains off. If it persists, there may be an underlying issue that needs professional inspection.

To change the light in the sun visor of a 1998 Volvo S90, first, locate the small cover or lens on the visor where the bulb is housed. Gently pry it open using a flat tool or your fingers. Remove the old bulb by pulling it straight out, then insert the new bulb in the same socket. Finally, snap the cover back into place, ensuring it is secure.

On a 1998 Volvo S90, the cabin air filter is located behind the glove compartment. To access it, you will need to remove the glove box by unscrewing the screws that hold it in place. Once the glove box is out, you should see the filter compartment, which can be opened to replace the filter. Make sure to check your owner's manual for any specific instructions related to your model.

The ECU (Engine Control Unit) on a 1998 Volvo S90 is typically located under the dashboard on the driver's side, near the steering column. It may be necessary to remove some panels or trim to access it. Additionally, the ECU is often mounted on or near the firewall, making it somewhat challenging to reach without proper tools. Always consult a repair manual for specific instructions and safety precautions.

In the 1995 Volvo 960, the radio suppression relay is typically located in the engine compartment, near the fuse box. It can usually be found mounted on or near the driver's side fender. Check the vehicle's manual for specific diagrams and locations for your model, as configurations may vary slightly.

If you're not getting much air through the vents on your 1998 Volvo S90, it could be due to a clogged cabin air filter, which restricts airflow. Another possibility is a malfunctioning blower motor or resistor, which controls the fan speed. Additionally, there may be an issue with the ductwork, such as blockages or leaks, that prevents proper air circulation. It's advisable to inspect these components to diagnose the issue accurately.

It's the hazard switch. I have a 1998 s90 and if you take a small screwdriver and insert it into the bottom of the hazard switch (on the dash) and gently pry it, it will pop out.

To add coolant to a Volvo S90, locate the coolant reservoir, which is typically found near the front of the engine bay, marked with a cap labeled for coolant. Make sure the engine is cool before opening the cap to avoid injury. Carefully pour the appropriate coolant mixture into the reservoir, ensuring it reaches the recommended level indicated on the side of the tank. Always consult your owner's manual for specific instructions and coolant specifications.

All models until 1999 use Mercon/Dexron fluid. Available in any auto parts store

You can flush the ATF yourself by locating the two oil-cooling-lines connected to the radiator.

Connect clear 1/2" inner diameter clear plastic tubing from Homedepot to the output line, and put the other end into a clear milk jug. TURN ON THE ENGINE and ATF Fluid will rush out of the cooling line.

After 2 quarts have come out the system, take out the ATF dipstick and fill 2 quarts of fresh new ATF. Repeat the process until oil in the output line appears clear/cherry red. This process may take 12-20 quarts of new ATF fluid. When you're done, plug the output line back into the radiator and check the fluid level from the dip stick.

If you over filled, you know how to take some out of the system by starting the process again.

{The rest is in the torque converter, the cooling lines and tank. The only way to completely change the fluid is to use a transmission flush machine which does its work by connecting to the transmission cooling lines and let the car run at idle. This is not the type of job for a do it yourself person. I have been a Volvo master technician for more than 30 years so please allow the dealer or a qualified repair shop to perform this job. The transmission in the 960/s90 and engine are almost bulletproof if properly maintained. Seeing one with over 300,000 mile is not unusual.} You will know quickly if you have the hose on the wrong line. Transmission fluid will go EVERYWHERE. Note: The trans lines are 960/S90 are notorious for stripping the threads. Also be sure to turn the engine off when you have 2 quarts in the jug
