It wouldn't be a fuse that would cause this. If the fuse was blown it would never work. It could be a relay that is bad and warming up or it could be a loose wire.

When was the last time the spark plugs were replaced? They sell an "Engine starting fluid" that you spray directly into your air intake hose to aid in the occasional start-up problem. Have used it before, works very well.

It is probably the relay for the fans.

You are describing a blower inside the car that does NOT blow or run at all? Very important, check the fuse? Is the blower resistor plugged in?
The resistor is located just below the glove box in the housing where you can see it. It sticks in an area where the air can have air passing over it from the blower running, will keep it cool. The blower switch must be checked.
Do not rule out the blower motor either. The blower motor can be powered up in place with jumpers to verify whether it is good.
I hope this is of some help to you.

Your '89 Maxima uses an R-12 refrigerant, commonly known as Freon. R-12 has since been discontinued for environmental reasons...newer cars now use R-410a.

R-12 is very hard to obtain these days. You can find it on eBay, but you will need to be EPA certified to purchase. If you can obtain the R-12 somehow, make sure you get it in a kit that includes the hose, tap, and instructions as this will save you some headache.

If you cannot find R-12, I would recommend converting the A/C system over to the new R-410a. Most mechanic shops can do this for you for around $200-$300. The price they quote you should include a complete evacuation of the system, changing the required fittings, and recharging with R-410a, and maybe some PEG oil, depending on the compressor used.

is normaly the chip in the key but in my firebird it hapened when the radio died

air conditioner may need recharge and to be checked for leaks.

Simple thing to test first would be to pressure check the radiator cap. Next would be to check for combustion gases in the radiator indicating a leaking head gasket.  It is an aluminum head and iron block engine and there is a possibility that antifreeze anti corrosionpackage runs out due to over age then fails due to too long in the engine it results in galvanic corrosion at the head gasket-commonly resulting in a failed head gasket.  There are other engines that are vastly more prone to this than the maxima engine.  If there is a leaking head gasket the gases could rise to the top of the system and block the water flow into the heater.  Listen for gurgling sound in the heater.

no heat or air could be a fuse issue

did you mount the thermostat properly... sounds like it is reversed

here is a picture of the proper orientation

did u try to disconnect the battery for 10 min or check wires make sure u got them all hooked up

follow the upper radiator hose to the timing belt end of the engine to locate the thermostate housing

sounds like the shifter cable

check the timming belt tensioner or on my 89 the crank was broke off flush in the harmonic balancer it was odd so u might check that

Make sure that the water level is correct at the radiator, first thing...

they are usually behind the glove box under the dash.

it goes inside of the housing unit. but when you put the housing unit on, the stem should be pointing to the engine

Make sure all of the cords were connected back to the battery so that everything will work properly as they did before the alternator was changed.

You may need a new alternator because if they are messed up, they will drain batteries and make it hard to start or keep your car running. Also get the starter checked because that can make it hard to start the car too.

check fluids. change oil. flush radiator.
