On start up the recirculation button and off button both blink simultaniously for a few minutes then stop. The blower motor is a bit noisy, when it is cool out it runs ok however yesterday it was in the high 80's and the blower would not turn on at all. Is my blower going bad or something else?

Thanks
Mike

The blinking lights indicate an error detected in the system. Usually it is the cabin temp sensor that gets dirty.

A noisy blower is not good. But, because it doesn't work at all when it is hot, it could be the resistor that has gone out. Neither the blower or resistor are cheap, but they are easy to replace.

Klaus, I pulled the blower, lubed the fan shaft, and cleaned the fan blades. That has basically eliminated the noise. Is the cabin temp sensor on the front of the dash or on top? Can it be cleaned? Who is a good source for the resistor other than the dealer, Erie Volvo?

Thanks for your response,
Mike

I forgot, check the fuses!

This is the resistor:

Tasca Volvo web site didn't respond this morning, they usually have very good prices also.

Some on this board have managed to repair the resistor, but my soldering skills are a bit lacking. A new diode is fairly cheap at radio shack.

The cabin temp sensor is on the front of the dash, just to the left of the ECC unit. Looks like a grill in the right most switch plate. To remove it, pull the radio out, then grab the rear of the ECC and yank it out of the dash. The radio can then go back in. Reach behind the sensor - note the angle of the electrical connector, it has to be at this angle to put back in! Slide your fingers down the barrel and feel for the 2 plastic push tabs, squeeze, and pull out the barrel. Do not drop it. Carefully clean the fan blades and remove the dirt/dust. Do not disturb the copper tube!
