Well my gf's 93 honda accord overheated the other day, first thing that came to mind was that it must of been the thermostat. Changed it out, did a full coolant flush and it was still getting hot after a long drive when you would let it idle. I checked the fans and come to find out neither the ac or radiator fan are kicking on and the ac just blows warm. Just the day before it overheated the ac and fans were working fine. Any ideas of whats going on?

I highly doubt this has anything to do with it but its been a little over 4k miles since I changed the oil last, I've heard something about high cylinder head pressure would cause this?? I don't know if that means high pressure in the oil system or cooling system. Any help is appreciated!

 

Check the fan fuses and see if they are blown.

 

I do a little mechanic and i'm also a Electronics technician.I have a 94 accord ex vtec. i bought it 5 months ago, I had the same problem you had.Now i only start and drive. your problem is most likely electrical. you probably will have to let someone with electrical ability troubleshoot it. It could be the ac pressure switch. theres a thermostat behind the glove box that was burnt on my car. paid $10 at a junk yard. theres also a control module behind the glove box, mine was burnt also. If theres anyway you can get the schematics, then that would help. good, luck.
