My car is blowing cold air but no heat at all. I checked the codes and it's throwing a B1 1-3-1. It's also throwing a A7 1-2-2. a buddy of mine is a mechanic but not too familiar with Volvo's. But he said that he thinks the B1 1-3-1 Driver's side air duct short is the problem. Is this the problem and how do I fix it?

If you car has the Automatic Climate Control, this may help.

B1 -131 IS Duct Temperature sensor driver side; short circuit to ground

Check to see if the rheostat is connected, and maybe replace it.


http://www.tascaparts.com/parts/1993/VOLVO...agramCallOut=14

Check Items: 17, 14 and 12


12 - Opens and closes the FLAP that causes air to recirculate in the cabin.

14 - The is the Temp sensor - If it can't sense the correct temp, the system will dumb out.

17 - This relay may have a effect of the Temp Sensor, but I'm not sure what it does.

Hey, what year is your car?

Does it have automatic heating and air conditioning? See PDF's

The A7 1-2-2 is the engine coolant sensor. REPLACE THIS FIRST, THE CLEAR CODES, TAKE THE CAR FOR A LONG DRIVE THEN RETEST FOR CODES
