you may be low on coolant/antifreeze.how do i use an OBD II scanner....?
Heating coil burned out?Sounds like either your thermostat or heatercore is shot. If the thermostat is stuck open (which they do when they break) then your engine is not warming up to tempature and then passing it on to the blower. If the heater core is shot or leaking (it is a small radiator usually hidden under the dashboard, it would cause not to blow warm air as well. The thermostat is only a $5.00 part, plus a gasket, and should not be much for labor, (though they drain your coolant). The heater core can set you back some cash, they have to drain your coolant and take your dashboard apart, and the core itself is over $100

Relace the heater core.How much money should it cost to replace and repair a radiator for a '92 Honda Civic?
coolant level,thermostat,heater control valveMost likely problem is blocked heater core in the HVAC under the dash. Check the hoses to this near the firewall to see if they are warm. Then check the flow at the outlet pipe by diconnecting it at the radiator. If you have flow then it is not plugged. Next step is to check vacuum actuators for your diverte doors in the HVAC under the dash for function. Common on all GM cars is the stuck Mod valve that opens and closes the diverter door for hot cold operation. There is a service buletin for this problem. It is a sefety issue as you cannot drive with cold air on a cold day trying to defrost the windshield.
My money would be on the blocked heater core, but you need to check all the functions and eliminate them 1 by 1 starting with the most likely and not the easiest.
Good luck with this.
how to replace clutch pack in ford limited slip rear axle?
check the antifreeze level first. If full then a couple of things. One could be a bad thermostat and the other more common problem on those is a plugged heater core. You can unplug that yourself if you want. What you need to do is first make sure the truck is cold. Let it sit for a while before you do this. On the firewall kind of in the middle and a little to the passenger side you will see 2 rubber hoses. Those are the heater core lines. Take them both off. Then take a hose and run water through one end of the heater core line (going into the firewall). Do this until the water comes out the other side clear. Then reverse the sides and do the same thing. Then put the lines back on take off the radiator cap and refill it with the proper mixture of dex-cool coolant. Then let the truck run with the heater on and leave the cap off so you can fill the system all the way. Once the system is full see of the heat is working. I have a strong feeling that this is the problem and will fix it.More Questions & Answers ...
