Question about 1993 Volvo 850

1 Answer

Heater fan does not work

My heater fan does not work all the time, it is usually hit and miss. The owners manual says if the recycled air and a/c lights flash on and off there is a malfunction in the ECC system. They do flash for about 20 seconds when you turn the car on. Is there an inexpensive way to fix this problem or can I fix it myself.

My tata indica model 2010 radieter fan not working.or heater light take extra time

bad engine thermostat, seems/
heater light? are you saying the cab fan heater is poor heat.
or are you saying engine heat is slow to hit 180F+ ???????
the fan only comes on when you over heat engine.
or if A/C is on.
the fan electric on newer cars is controlled by the PCM
if the coolant never hits the programmed trip point, the fan never goes on. (bad thermostat or air in the cooling of engine block)
if coolant really is hitting say 220f, at idle or more, (fan test is in FSM read that page)
then the ECT may be fibbing. Scan it.
scan the PCM does the ECT read , true reality or not.
that is it.

Turn it on, Put the heater on high. While the heater is on high hold down the rear wiper, rear washer and recycle air buttons (all at the same time) for 5 seconds. It will reset your heater computer.

Defrost Problems the window freezes up from the outter edges In..

The rear window defrost could be a fuse or relay, if you have the owners manual that will show you which fuse or relay it is.
Is the engine temperature getting up to normal? Where do you have the heater controls set, are you pulling fresh air in from outside, or are you recycling the air inside the car? You have to pull in outside air, or the windows will continue to fog up. That car has a "Cabin Filter" which fiters the air coming into the heater system from outside. Have you ever changed that? It's usually located under the panel by the right windshield wiper. Check the owners manual that should tell you about it. No owners manual go to?, That will give a list on the salvage yards in you area that have a used manual.

Display on dash

For the dash display, if you're finding it to be intermittent, where it lights up sometimes and other times it doesn't, or if you have the driver information center that displays all kinds of info, but it's missing pixels, this is a common failure. The only fix is to buy another one, and they're very expensive (around $700).

As for the heater, turn on the system by hitting Auto or one of the fan speed buttons. Use the + and - buttons below the temp display to change the temp setting. If the heat doesn't heat up very well, you may have either a thermostat stuck open, or a failed heater core.
