Home1989 corvette heater blows cold air even though both lines are hot going to the firewall do you have to change the heater core and if so how do you do it?
I would say that your heater core is ok...it sounds like you have a bled door promlem in the dash.

I have a '91 and I believe they're about the same though. The heater core is back inside the glove compartment. You'll probably have to remove the door/tray itself. To get it out you have to disconnect the coolant hoses going through the firewall (engine side). After that there really shouldn't be much to it.
There was never a production Corvette made of aluminum. In 1972, GM built the XP 895 concept corvette from aluminum though.
remove panel cover in middle of car under dash where the heater core hoses are at that go through the firewall under the hood, this is where the heater core will be located at inside the car start removing screws, until covers come off remove the hoses first though i have to replace the heater core in a 93 Bonneville tomorrow good luck
In the engine bay, remove the inlet and outlet hose from the firewall for the heater core, get a heater hose connector that matches the hose sizes (fair warning they are 2 different sizes but i cant remember) and just join the 2 hoses together with the connector and some clamps. you wont have heat or defrost by doing this though.
It is under the dash board and it is extremely difficul to change. Shop labor and parts will cost you aroud $350.00. I just had mine replaced. It can be done, though. Took me six hours, three of which were the stupid dash. You'll see the two hoses in the middle and the bottom of the firewall.
Nope. It tried though!
no not from the factory though a few dealer conversions do exist
Heater core plugged? Heater core airbound? Thermostat not opening to allow coolant flow?
you can get though a fire wall cumpter network by pressing random buttons or getting a teachers username and password!
A firewall prevents unauthorised access to your computer over the internet. It stops people trying to access the programs and personal files on your hard-drive. A firewall isn't enough though - you should use a good anti-virus program in tandem with your firewall.
I have the Chilton manual for this vehicle and it appears as though you will need to disassemble the dash to get to the heater core. Before you do this, make sure you disconnect the hoses on the engine side of the firewall and try to blow out as much of the remaining coolant to avoid spilling on the interior later during removal. The duct will have to be removed from the vehicle so whatever it takes to get there on your car will have to be done to get to the heater core itself.
I believe the first edition Corvette was introduced somewhere in the 1950's, so about 64 years ago. Newer models are released nearly every year though.
I have a firewall and can still access limewire, it just wont let me download some songs as apparently they contain viruses. It may differ depending on your firewall operator. dont worry though as there is a lot of songs you can download with the firewall, aswell as a few you cant.
No the evaporator can NOT be accessed from the firewall, the only way to access the evap is to remove the dash. you can get to the expansion valve at the firewall though and replace that and the seals. But that is the only thing you can get to at the firewall. hope that helps.
well it out preformed the corvette in both power and handling, but that's not the one with the 403 in it though.
To bypass a Netgear Firewall for going to a particular website like DevianArt, a person has to turn the firewall off. This is not recommended, though. A person can go into Internet options under Privacy and Allow the DevianArt website to run without turning off the firewall.
if you are referring to the door that controls inlet air vs recirculated air, it is located inside the heater assembly its self. if you're trying to figure the hot/cold mix, there ISNT a mix door - heat control is adjusted by limiting the flow of hot engine coolant through the heater core by a mechanical ball valve ( usually found on the front of the firewall, right where the heater hoses pass though)
Most likely, the larger volume of air, and its greater speed at the high setting is sucking all the heat out of the heater core that it can deliver. That is, the higher airstream "dilutes" the warmth of the heater core. The heater core may be clogged in the parts where the hot water runs through it. You could try power flushing your cooling system . . . on the cars I have had (Dodge, Plymouth) it was much easier (though not real easy) to simply replace the heater core, which on those cars was behind the glove compartment. If you look under the hood, you should see 2 black hoses going into the firewall near each other. That would be hwere the heater core is.
I think it's up in the left rear wheel well. Don't quote me on it, though.
This is actually more common temp fix than you might think. It shouldn't hurt anything. It is only temporary though. You will have no way to heat the vehicle come next winter. Just get a piece of small pipe or tubing of some sort and a couple of worm clamps and seal it as best as you can. It is gonna be a real b-tch to change the the heater core. Good luck. Brad.
just pick a spot that's decently clear on both sides of the firewall. preferably on the battery/fuse box side of the car
On my 1999 Mercury Tracer, the fuel filter is mounted on the firewall. It's on the driver-side, on the passenger-side of the brake cylinder. I don't know how to get my hands in to change it though. Jonathon
For an electric water heater on alternating current, there is not 'positive' or 'negative'. There should be terminals labeled hot and neutral, though.
GM Heater Line Quick-Connect Release Tool this will do it. Otherwise you need to try and use a hacksaw to cut it off, though I wouldn't recommend it, might cut the line into the heater coil
It could be the high speed heater motor relay is stuck on or the switch itself is broken.
