check the alternator mine when out one time on the ride home and those were some of the affects.
have you checked the fuses? if so, maybe the heater core needs replacing
Have you checked you heater control valve or heater core if working properly.
there is no fuse for a block heater the block heater is installed in the oil cooler on side of engine a lead goes from heater to plug in at front of engine this heater is plugged into 110 power from house.it is not controlled by anything in the truck if it is not working have the wiring checked and have the heater checked wiring for block heater is sold separate to heater,and costs about 80 bucks,heater cost about 70 bucks
You have to be more specific. What is not working?
Disconnect and isolate the negative battery cable.Remove the center bezel from the instrument panel.Remove the four screws that secure the A/C-heater control to the instrument panel.Pull the A/C-heater control away from the instrument panel far enough to access the connections on the back of the control.Disconnect the vacuum harness from the A/C-heater control.Disconnect the wire harness connectors from the A/C-heater control and remove the blower switch......
Two good indicators of when to replace the car's thermostat: * When you have to run the heater (no matter what time of the year) in order to keep the engine coolant from overheating, * When you no longer get ANY heat from the heater core.
To replace a 1988 Dakota heater core, first discharge the A/C. Then remove the lower instrument panel before removing the heater box unit.

It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.
