Question about 1995 Pontiac Grand Am

Heater only blows thru dashboard vents, won't defrost

I own a 1995 Pontiac Grand Am. The radiator cracked and I had to have a new radiator installed, yesterday, 31Dec08. With the new radiator, the heater works okay, but I cannot direct the heater airflow with the right heater control knob. The heater only projects an airflow through the instrument panel outlets. When I put the dial to defrost, no air comes out of the defroster vents, the airflow continues to come out of the instrumet panel outlets only. It is as if the control knob only operates in the "vent" mode, no matter where I position the dial.

98 Pontiac grand Prix 3800, is it possible for transmission to leak into the radiator and mix in with the antifreeze?


yes --it is a common thing
the transmission oil cooler is in one of the radiator tanks and have a habit if cracking allowing the transmission oil to mix with the coolant
the fix is a new radiator and a very good wash out of the cooling system ( heater included)
I suggest that you use an accredited radiator shop and have then do the flush and the radiator replacement

Where is the radiator drain plug located in a 1995 Pontiac Grand Prix?


There is no drain plug or valve on most modern radiators. You have to remove the lower radiator hose in order to drain them.

Why wont the heater blow out hot air in my 1995 pontiac bonneville. it will only blow cool air


If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

My pontiac grand prix is a 1995 the air works fine but will only blow threw floor and defrost vents how can i get it to blow threw dash vents


Vacuum vents not working: Your vent controller is not working. Is theair coming out the defrost vents? If yes, this is the default when there is novacuum to the switch. In this case, check the small plastic vacuum line that isconnected to the engine intake manifold and going into the firewall. Make surethis line is connected to the manifold and the hose is not cracked. If this isgood, go inside the car and see if you can trace that line to the control switch. If theline is good to the switch, see if you can pull the vacuum connector from theswitch for troubleshooting. with the engine on, check for vacuum on the linefrom the engine with your finger. If the vacuum is there, your switch isprobably leaking and needs to be replace. Any other questions, please reply.

My 1997 Grand Am is leaking antifreeze. It overheats and smells like burning antifreeze. We had a new water pump put on it and a new heater core put on it 4 days ago. Neither of those solved the problem....


it maybe a hose not installed correctly, if it is a v-6 check the intake gaskets for signs of leaking, when you over heat the engine, automatically replace the thermostat, the cooling fans may have a hand in the overheating issue, they may not be turning on due fan motor failure, check cooling fan fuses, very rarely does the coolant temp sensor give out and if it has, that would also be the reason the cooling fans are not coming on, a cracked radiator is also common on gm or any other radiator with plastic tanks. good luck
