Question about 1998 Volvo S70

Open Question

98 Volvo S70. My heater fan only blows occasionally. When breaking or accelerating or when I hit a bump in the road. Could it just be a connection is not tight? I recently had the heater core unit replaced about 5 months ago and it has worked fine until it got 10 degrees here. PLEASE HELP....I'M FREEZING!!!

You must take the car to a Volvo dealer so they can reference the code from the VIN number. If you call it in, they only assume you stole the radio. Sometimes you have to prove you own the car.

SOURCE: 98 volvo s70 stalling out, then finally after a day wouldnt start

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.

The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

SOURCE: Replace Heater Core for Volvo S70 (1999)

It is your heater core. I fixed mine for $144. Ordered the new part on Ebay and followed these instructions http://www.volvospeed.com/vs_forum/index.php?showtopic=9717 It was very simple, I'm a middle age grandmother! The hardest part was cleaning up all the antifreeze. You will need a shopvac, a small one is $20 at WalMart.

Sure sounds like the heater core, the only other thing would be some time of leak that is raising the moisture in the car is the floor board on the passengers side wet? If not look toward the heater core.

You will likely need the heater hose junction (Volvo p/n 3522035) since it always leaks and it connects the heater core to the heater hoses on the firewall. The kit usually contains the retaining clips, but not the O-rings to connect to the heater core. You will also need the outlet and inlet hoses (9186847 and 9186849). The length, angles and configuration of these hoses will help you understand their orientation in the engine bay. They can only go on one way. Else, they won't connect to the pipes from the engine.

Volvo s70, 1998, heater not blowing hot air


Are you getting coolant flow through the heater core? These cars have common problems with heater cores but they are easy to replace. IPD has a Video on U-Tube with step by step instructions. Also if you are in very cold weather have you checked your anti-freeze? I saw a Toyota last year freeze completely because of no anti-freeze. It took days to thaw out the heater core and they were lucky that the ice did not blow it apart. It took me hours of starting it and running up to a low temp and shutting it down to get it drivable.

There is a bad connection somewhere in the circuit. Could be the motor, the fuse/fuse box, the switch or a break in the wire that makes occasional contact.
