Heater is not working!

If your blowing fuses, then you either have a short or a component drawing too much current and you will have to isolate what's causing the fuse to blow. This guide can help us fix it

Please run down this guide and report back.

Start by making sure your level of coolant is right; if not add some. If adding coolant doesn't make a difference, replace the thermostat and let me know if it fixes the problem.

Hello,
Usually a lack of heat indicates one of the following problems:
-Low coolant (check the level)
-thermostat stuck open (when it happens your engine takes a very long time to reach normal operating temperature)
-clogged heater core (check the two small rubber hoses connected to it thru the firewall with engine at normal temp; one will be very hot, the other will be significantly colder. If both are very hot then you're fine).

Normally one would expect a thermostat, but with engine at temp, quickly touch the heater core hoses. If one is hot and one cold then heater core is blocked. If both are cold then thermostat.

SYSTEM TESTS
BLOWER MOTOR DOES NOT OPERATE
Check fuse No. 64 (30-amp) in Battery Junction Box (BJB), located in left rear corner of engine compartment. If fuse is blown, replace fuse. If fuse blows again, repair short to ground in Green/Orange wire between fuse No. 64 (30-amp) in BJB and terminal No. 1 of heater blower motor. If fuse is okay, go to next step.
Turn ignition off. Disconnect blower motor harness connector. Turn ignition on. Measure voltage between ground and terminal No. 1 (Green/Orange wire) of blower motor harness connector. If battery voltage exists, go to next step. If battery voltage does not exist, repair short to ground in Green/Orange wire between fuse No. 64 (30-amp) in BJB and heater blower motor.
Turn ignition off. Measure resistance between ground and terminal No. 2 (Black/Red wire) of blower motor. If resistance is 5 ohms or less, replace heater blower motor. See BLOWER MOTOR under REMOVAL & INSTALLATION. If resistance is more than 5 ohms, go to next step.
Disconnect blower switch. Measure resistance between terminal No. 2 (Black/Red wire) of heater blower motor harness connector and terminal No. 4 (Black/Orange wire) of heater blower switch harness connector. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in wire between blower motor and blower motor switch.
Measure resistance between ground and terminal No. 6 (Black wire) of blower switch. If resistance is 5 ohms or less, replace blower motor switch. If resistance is more than 5 ohms, repair open between blower motor switch and ground (located at left "A" pillar).

Check to see if heater core hoses are getting hot.2 hoses going through firewall into passenger compartment. If they're not. Your core is blocked and needs flushing/replacing

Check/replace the thermostat. Flush and refill coolant system and heater core. When refilling make sure no air gets trapped in the system. You may have a slight blockage in the system

If the fan isn't running, check to make sure it is getting power. If it is, replace the motor. If there is no power, trace the wiring back through the resister, relay and to the switch to locate where the power is lost.
