good evening my name is ***** ***** I will assist
the gear inside the antennae has stripped out and causes this condition. very common for these older units.
the antennae has to be replaced as an assembly. there is a relay under the dash below and behind the glove box that operates the antennae. remove the wires from the relay and it will stop.
as far as the heat goes, make sure the coolant is topped off to the proper level. run the engine at 1500 rpm for 5 minutes to bleed the heater core of air.
as far as the power locks, if it works with the remote, I suspect a power door lock switch. you need to verify power to the switch and that the switch is sending a command to the acuators
please dont forget to rate me as it is the only way I get paid for my efforts
