Does your heater motor run when you turn speed dial ? Have you checked the two hoses that run from the engine compartment to the heater core ? When car is at operating temperature, carefully touch both hoses which should be warm or hot. If only one if hot, then you may have a bad actuator. If both are hot, you may have a clogged heater core or none functioning heater motor. or resister. If motor is not working, check fuses, if good, then check for power at the switch and then at the heater motor.

The instrument panel should not prevent it from starting. I would surmise that during the process of installing it either a harness got disconnected or a fuse was bliwn. Check all fuses in both fuse boxes first. Then reply with the following details: 1) does it turn over (crank) but not start? 2) you should be able to hear the fuel pump run for a few seconds when the key is turned on-does it? 3) any problems before the repair?

you gonna have to find the switch and check the wires are connected, if they are connected then it could be a fuse or a relay switch my be bad. there could also be a short or ground somewhere and wire tracing can be annoying

You need to contact the maker of the security system.

I had the same problem with a Mercury. It was the starter. Had a bad field winding. When I would try to start the engine the battery cables tried to straighten out. Might take a look at the battery cables when trying to start the engine.

Probably not. It is a simple system wherein hot water flowing through it makes heat, and no water makes no heat.
