Scan it from the OBDII System to find out for sure or remove the Alternator and have it tested at your local Auto Parts Store.

You can try a Hard Reboot, remove the battery cables from the battery, wait 20 minutes then make contact with the + an - cables together for at least 10 seconds. Normally you would want to run a diagnostic on the new computer if it cam out of another car just to erase the codes from the other car.

It sounds like the memory's low voltage supply is cut off.

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.

Check for vacuum leaks. I will bet that you have a bad or leaking vacuum hose between the intake manifold or PCV System and the Evap. System.

Have your Cooling System pressure checked. Also check your oil and anti-freeze. If the oil is milky or the anti-freeze is oily you have a blown head gasket. Watch for white smoke (Steam) coming out of the tail pipe after it is warmed up. If you have white coming out that is coolant, black is fuel and blue is oil. After the pressure test if there are no leaks detected in the hoses then get a compression test to see which cylinder is leaking.

You can not check the timing with a timing light. IPD has a Code Reader that will give a running diagnostic that includes Timing for $80 search ipdusa.

First check your fuses and clean them and coat them with Dielectric grease, then try replacing the Relay if that does not fix it.

1998 Volvo S70 | Answered on Jan 28, 2015


The Cam Relay will be at the Driver side end of the exhaust cam. You will need to remove the upper torque mount to get to it.

Make sure the Gear Shift is all the way into Park. You may have to jiggle it.

I have never seen a fusible link on a Volvo.

IPD's website has a great video on the site that shows you step by step how everything comes apart and goes back together to change Heater Cores. It would be easier for you to watch that than have me explain. You have probably missed a screw somewhere.
