Hi Guys,
I am having a problem with my A/C. I have a 98 V70 non turbo, with electronic climate control. The problem I am having is the A/C blower will run very slowly or stop all together. What happens is when I first turn the car on I usually have the A/C on 72 and auto, the fan will ramp up to full speed and after a few minutes it will ramp down to a very slow speed, shut off, run at a slow speed, run full blast and so on. I know my compressor is still running because I can hear the clutch pulling in and out. So I have concluded it is either the blower motor or motor resistor, but which one. Do you know of a trouble shooting method as opposed to trial and error. Any help you could give would be much appreciated.

I live in Phoenix, AZ and it has been 110+ for the last few days and basically the car is non driveable.

Thanks alot for the help.

ps, I have an evaporative leak, I can hear the bleed down up front, any ideas there.

 

I bet it it the blower motor, mine was doing the same. Easy fix.
