Need some help. Have 2000 Accord Coupe w/3.0. Temp gauge does not work (just sits at C). Originally cooling fan would not work either, but now does, after replacing thermal switch.
1) Checked fuses - inside & out - good
2) Checked fusible link - good
3) Bypassed/jumpered fan - works
4) Replaced ECT sensor (Driver's side, beside EGR).
5) Bypassed/jumpered Thermal switch - fan runs
6) Replaced Thermal switch (Driver's side, by hoses)
7) Cooling fan now works, but no temp gauge change.
Any suggestions? Just bought the car, so have no history. Thanks.
