acces. fan 86' 300E need help !!!!
 

OK the fan is't coming on and I know the fan works it's self because I've unplugged and plugged it directly to the batt. and it came on, no I heard it has a switch, and a relay that could be bad.
how can i test them so i don't buy both i think they are about 40-50 bucks each. any suddgestions?

I'm at work for now and if you could maybe email me at cspawn1@txu.com

thanks every one....

Speedy:

Which fan are you referring to? Aux Cooling Fan or Blower Fan?

the cooling fan...

Do you know where the switch is located? You probably got the two pin switch. This one can be troubleshooted by shorten the switch.

Here's a post where a I did write how you troubleshoot the switch

I know it's not the same engine as in your car but I can't believe the switches are different. Dunno for sure...

hey thanks for the info ...wish I put this thread on about 2 weeks ago it's now at the shop for it but as a favor from the mechcanic, it should be free but if he charges me I'm going to do it my self.....
