Pin Outs On A 2000 ECC Motor Calibration

you could match the shaft position of the old Actuator with the new one by simply using a 9 volt battery

Is your Volvo’s climate control clicking from the dash when you adjust the cabin temperature? If so, it could be the blend motor. Blend motor = ECC motor = the thing that blends hot and cold air to give you that perfect 70 degrees from the vents.

If Your Climate Clicks…

The clicking means it’s at the end of its travel, and you need to take it out and use a 9v battery to move the arm to one side. Longtime MVS member JBRollo took his out and reset the travel and eliminated the clicking:

Does Your XC90 Have Nivomat Rear Shocks? How to Tell

XC90 Nivomat Rear Shocks

MVS Volvo Forum member 2003XC90 has a question about his — you guessed it — 2003 XC90. Specifically, he needs to replace the rear shocks. The problem is that there are more than one possible replacement shock for this year XC90 rear shocks. The variable is if your XC90 has Nivomat shocks or not.

The rear shocks or struts have worn out on our 2003 XC90 after 171K miles.

The Volvo dealer tells us that if the shocks are “Nivomat” shocks, then they cost $585 each. Ouch! They told us that there is a silver plate on the firewall or under the fenderwell which will let you know which shocks you have on your vehicle.

How to tell if your XC90 has Nivomat Rear Shocks

Luckily, member Stravlr knows, and tells:

Open the hood. On the drivers side look for the VIN Plate below the VIN there is a long string of number typically starting with a 33, 34 or 35. In that string do you see the number 26? If you do then you have Nivomat shocks, and you can get them new for about $380 (ea) on Amazon.
