No Heat In My '89!

[suprasweetie]

I've Had My Supra For About 5 Months Now And All Has Been Well Until About A Week Ago When My Heat Just Stopped Working. I Was Driving To Pick Up My Boyfriend And My Car Was So Warm, I Turned It Off When I Got There Then When I Went To Turn It Back On I Got Nothing. You Can Kind Of Hear That The Vents Are Switching From, Like, Defrost To Full Heat, But No Air Comes Out. Someone Help!

No hot air or or just cold air? If it's just not getting hot air, I suspect your Heater VSV has failed. This is easy to replace/fix. Just say which problem it is.

Maybe check your thermostat too. Not too sure.

[Jeeves]

Nah, this is a known issue with Supras. 99% guarenteed not to be thermostat, it'd show up in other ways.

Maby the vaccume line to the VSV has become cracked or come off.located passenger side upper fire wall.

It sounds to me as if No air is coming out at all.. Which if that is the case, the heater VSV is not the culprit..
The things ide check are
1. a blown fuse or circuit breaker
2. bad heater relay
3. bad wiring or loose connection
4. a bad blower motor

if you can get cold air and not hot your blend door is probally stuck
