Radiator Fan Not Working...
I have an '83 auto and just recently the raditor fan on the right side stopped working. I noticed when the car got really hot one day on the trip home from work. I reached in to spin it with my hand and it would barely spin, almost seized up. I replaced the fan but it still won't come on when the car warms up. I checked all the fuse, all good. but I'm not sure what relay to check. I can't seem to make sense of the wiring diagram because of the two fans and they're called something different. (in stead of fan 1 and fan 2)...Not sure what else to check...Anybody BTDT...
TIA, Mike D. |

Try seeing if the second fan goes on when you turn on the air conditioner. If it does, then you should probably replace the thermofan switch. It's a quick change and it's not that expensive either.

check fuses in both fuse locations.

Two fans, two fuses, two relays. Temp switch on radiator with one set of contacts.
Check fuses 3 and 5 on the 9 fuse panel. Count from the door. http://944-world.com/earlyfusepanel.html Also check relay #1 and relay #3. Bet it's a fuse as your old fan seized up (front ball bearing). Later 6 blade fans have a sealed ball bearing. Earlys don't.

All fuses are good. Is there a trick to getting the relays out? tried pulling the #1 relay and felt like I was going to pull the whole board out..
Maybe I'll just check/change the Thermo Time Switch... -Mike D.

I've bent the tip on a small diameter long shank screwdriver so as to get under the edge of the relays to pry up. Otherwise I tend to pull the covers off.
