My fans would run after start up for a few minutes then shut off and never paid them no mine. So, I never noticed that they weren't working until I got stuck in bumper-to-bumper traffic! Now my question is...is there a fuse blown and where is it located? If not, what?
I have limited mechanical ability and worse electrical knowledge. Detail instructions: where and how, pics would be nice, too.
Thanks

It should be a LAW that if you buy one of these cars, (now 22-28 years old) that you also buy the appropriate FSM matching the model year to go with it. Do you have an FSM? Model year matters some too. What model year are we talking about?

Amen! And in this case the Section 8A Electrical Diagnosis Supplement to the FSM.

To help the OP out here is what I referring to.... Start with the diagnostic trees in the post below this one.

Paul thanks for the reply. When I posted, I checked for grammar, spelling, punctuation, yada, yada but forgot the damn year. I can only blame it on old age, CRS and...I forgot the other! I do have the two big red books (FSM) is that what you are referring to?
ccmano thanks. Thanks for the reply and pics. Is the Section 8A Electrical Diagnosis Supplement to the FSM a different book? Sorry for such a dumb question but I don't have the FSMs with me.

So I have a 95.

Section 8A Electrical Diagnosis Supplement to the FSM is a separate book for 1990. Not sure about 1995. Might actually be in one of your books. The photos in the top post are from the supplement. The post beneath has photos from the 1990 FSM.

You mentioned the fans run for a few minutes after start-up. So the electrics powering them is OK. Do they run when the AC is making cold? they should be running continuously then if the system has adequate R134.

I have been put down several times by members here and on the other site for suggesting a FSM is needed.
Thank you for chiming in. There are so many variables in diagnosing a problem that a guide is, in my opinion, necessary to eliminate the possible causes in an orderly manner.
The FSM's may not always be 100% accurate, nor will they lead you to the problem every time, but they will assist in elimanating a lot of probabilities.
The information obtained from other members is invaluable, but a certain "method to the madness" needs to be followed.

My favorite ('lectric chit) troubleshooting tool is the electrical schematic. After that, it's my trusty VOM. (Back in my radar fixin' dayz in UNCLE SAM'S HAZE GREY YACHT CLUB it was a schematic, Simpson 260 (VOM), and a dual trace Tektronixs 545 o'scope. But, I digress...)




As a matter of fact, that ol' Tek scope would still come in danged handy for troubleshooting certain dynamic automotive phenomenon, e.g., O2 sensor performance, TB linearity, all kinds of sensor performance i.e., ignition circuits and injector dwell....

Are the red things on that where you tie up the horses when you go for a beer?
Merry Christmas!
