Sounds like the heater control unit is going bad. I believe this unit has a digital/vacuum control unit which explains why you are only getting hot out of one vent. Try the salvage yard or ebay for a replacement unit. They are non-repairable...

no just not hooked up right. some cars have chassis ground speakers which can be a pain. best to let a pro do it and watch.

Sounds like you have a severe vacuum leak. Poor vacuum will cause the trans to shift hard, very hard, and will also cause driveability concerns. Check all of your vacuum lines make sure they are intact, and not broken or leaking, and replace any that look questionable.

4.5 Qts. Put 4 Qts in and check it, just add .5 of a qt until its full.

CHECK HVAC FUSES.ALSO BLOWER RELAY.IF ALL IS GOOD PROBLEM IS IN THE HVAC SWITCH.IT COULD BE FAULTY.

you have to put a wrench on the belt tensioner rotate it all the way back, this allows the room you need to install the belt

HI begin by disconnecting battery , remove alternator then remove the two heater hoses attach to tensioner bracket by removing the to front screws, you will lose coolant so put a pan on the bottom .Then remove bolts attached to tensioner bracket.it will require a little force to pull out yest make sure you got all the bolts out before applying force. Here is a picture tensioner and bracket assembly so you can see what bolts to remove. let me know how it turns out it is not so bad to do

is that a problem? I believe that is the top speed until the ecm cuts fuel to the engine. mainly because of the speed rating of the tires.

check your fluid level..(transmission), nothing will work if the fluid is too low....if that's ok, then the linkages might be off alignment, also there is a vacuum controlled valve that is mounted outside the transmission casing on the transmission that controls your shifting as well....(modulator valve) if the vauum is missing, this will also give you trouble....you might have a broken or clogged vacuum line, a bad modulator valve..etc...., but first check your fluid level...that's most likely causing your problem
good luck

You have an engine Vacuum leak. It might be as simple as a vacuum hose.

take spark plug wires off the plugs ONE AT A TIME. remove the plug and replace it, then follow the wire to the coil pack and replace it with a new one and do this for each one, how ever, when it comes to the back plugs, your going to have to do it from underneath...

Putting the car on ramps or jacking the entire front end up.

get a can of carberator cleaner, and a bottle of white lithium grease, the spray kind,

spray the throttle springs really good with the cleaner, let it dry, and spray the lithium grease on it, and work the throttle back and forth, this should solve your problem.

It is a mute point because you can't do this yourself. Your system has air in it plus moisture. All that need sucking out with a refrigerant gas recovery machine to create a very strong vacuum, then the system is checked for leaks. Only then is the refrigerant gas installed by weight. Freon is the brand name for a gas that is no longer used. There is a sticker in the engine bay that tells you the weight of gas and the amount of oil. This explains, take it to a shop that does AC. https://www.fixya.com/cars/r29878326-recharging_vehicle_air_conditioner ..

The blower resistor may be going bad and need replacing. Does it do it only on one or any fan speed? I'm not sure where that particular part is located for it has been number of years I have looked at vehicles older than 18 yrs. but I hope this steers you in the right direction. Jesus loves you, John 3:16-17 (KJV)

I think you could use this manual method instead.. My nephew used it to repair my car and it's totally perfectly fine now. Here's the website he bought it from. www.reliable-store.com
