i have seen the power distribution box connectors for the fuel pump relay and fuse on the underside of box get hot and short out. need to remove box and check. If no signs of melted connector. you will need to locate the short.

You may want to check the two water houses that feed the heater core. they both have to be hot. (they are usually located next to the thermostat housing.) If they are cold first check the coolant level. Fill up if needed, then you may have to check of there is an obstruction by the housing or the heater core is clogged up. I would first disconnect the hoses and see inside the thermostat housing with a lamp. Also blow some Air inside the heater core to see if flushing is needed. Well if those hoses are both hot then that must be a problem inside the cabin with the vents selection. Either an electric switch or cable. But there are already a few things to check first.

You should have a 12volt test light. Then just turn on the key and check all the fuses. Probe with the icepick end on each side of fuse. A blown fuse will light the light on one side but not the other.

This is common for the turn signal/multifunction switch to do this. They have little plastis tabs that are hit when the steering is turned to cancel the signal. If those tabs have worn down or broken, the switch continues to work but will not cancel. Replace the switch if this is a major annoyance to you. Let me know if you need instructions or diagrams.

I had a similar problem with my Honda, it turned out to be the ignition switch. I found a used one on a online used auto parts store.

Try checking speedometer cable by unhooking both ends and spin it by fingers, if cable is good both ends will spin, and guage could be bad or where it attacheas to transmission that part could be bad to.
