I have a 1990 Honda Accord EX 6cyl Automatic...used to have AC, but hasn't worked since I owned the car (bought at auction for a great deal 2 years ago.) The heater seems to be developing a mind of it's own...sometimes it works, sometimes not! One day I'll start it and it's blowing hot air, etc...next day...the fan won't engage to blow anything! It might decide to start up while I'm en route to a destination, but...who knows? When it DOES decide to blow, the toaster seems to be working just great...the switch selector will dial high or low, etc, and all of the buttons designating defrost or whatever work fine. Rear def in the glass still works as fast as ever. It doesn't seem to be the core, but a fan-related malfunction...wiring, or a resistor? Can anyone suggest where I should begin to resolve this problem? I can't afford to pay a shop to 'track' and replace parts with guesswork, so an educated theory might help!
Thanks for any assistance!
It would only happen in winter, eh? Char

The trouble is intermittent so, the first thing to check is the wire connectors at the fan. Make sure the connection is clean and solid. If this don't do it the next thing is to check the connection at the fan speed switch. Same thing, make sure it's a clean and solid connection. If that don't do it, then replace the speed control switch. That's the end of the cheap and easy stuff. Next and last effort would be replacing the blower motor.

If it is more likely that the fan will work after the car warms up, it's probably the brushes in the fan. There is no real way to tell that it's the fan for sure; but start with the fuses, then do the fan. If you go over a bump or jiggle the switch, and it works, then it is more than likely that it is the switch, which is expensive, i think. Unless you have really low miles, you live in the Dakotas, or you travel long distances, I wouldn't drop a dime on a 16 yr old car. If you must, it sounds like it's the fan.

How many miles are on the car? If it is under a 160,000 miles it probably isn't the starter, could be just a weak battery or poor (corrosion) at the battery terminals. You fail to explain the problem adequetly, Does the starter turn over the engine everytime but it seems the car takes several attempts to crank it? If thats the case it is most likely the rotor under your distributor cap. Cheap fix,,,it could be a number of things. An experienced mechanic at the Honda place could probably diagnose it while you watch. I haven't ever had a key switch in any of mine go bad, but it sounds like yours could be worn. It is hard to diagnose the problem over the phone or internet, it would be easy if I could put my hands and eyes on it. Don't replace the starter without checking battery with load tester and check it for clean tight connections first, you can't tell by looking at it, you have to clean them to be sure. If the distibutor cap and rotor have not been replaced in 200,000 miles its time to replace them as preventative maint.

I would use a multimeter and test the power going to the fan when it doesnt work. That will allow you to know if it is a fan problem or something else.
Test the fuse box where the fan fuse plugs into when it stops working also.
