i just replaced the engine in a 90 accord with one from a 91. i rolled the driver window down so i could start the car without opening the door. i then changed the temperature sensor because it was bad. now none of the windows work. i'm pretty sure its coincidence it happened that way. i checked the fuses and everything looks fine. i checked the relay under the hood. i swapped window switches. nothing. also the temperature gauge stopped working after replacing the temp sensor. and the tach and speedo don't work now. all wiring appears to be in place though. if anyone has an idea please help.

 

check the under dash fuse box. it will be a 10 amp fuse that will most likely be blown. it controls, windows and instrument panel. i think its labeled back up light.

 

yep, that was it. everything is working now. thanks for the tip.
