Pulling dtc codes
Okay, I'm pulling codes in my climate control. It started yesterday when I turned on the blower and the Rec/AC lights started to flash and the blower wouldn't, well, blow. It's blowing as of about 30mins ago though...
I'm pulling the following:
417: Passenger side interior temp inlet fan seized
418: No control signal to blower fan power stage
WTF does all that mean and how can I fix it? Thanks
Also, I'm pulling a 122 in the B2 socket. According to the service manual, this is a "Speed Below Minimum/No Signal" but later on it states: "Code 1-2-2 is stored when ignition is turned on. It remains until vehicle speed is greater than 22 MPH for at least 15 seconds. If code remains after a road test at speeds greater than 22 MPH, control unit is not getting a speed signal." Not exactly sure what to do here as the cruise has been working fine.

As related to the other thread : https://volvoforums.com/m_38497/tm.htm. Code 418, it sounds like your ballast resistor the one on the right (power stage relay, common problem, replace here: http://fcpgroton.com/VolvoAC/volvo850ac.htm (9144354 Blower Motor Resistor w/ Electric Climate Control $99.00 Genuine Volvo) Code 417 remove handle and blow out usually will fix problem. Do you have a haynes manual? Read it, it has good info. Even better check this out http://www.matthewsvolvosite.com/cha...97cbe47d75b72e, it for a 95, but I do not believe there is much difference between 93-95.
Hope this helps!!

After test driving did you leave it run when checking the codes in the ABS again?
It will always be there till over the reccomended speed.

No, I didn't leave it running when I checked the codes. I was experiencing the flashing Rec/AC lights and while I was checking those codes, I took a peek at all the others.
