Help with Nissan Sunny 90

Wave everyone.
I have a Nissan Sunny 90 Twin Cam Japanese (transformed the steering wheel to the left)
I would like to know if someone can give me data to repair heating and air conditioning. Above all I need to fix the front glass.

I would thank you very much if someone could help me. I am getting in this to do it.

Greetings

For the year, the safest is your Motor Blower, they have to get a positive and a negative one, the negative is constant and if the positive comes to you then change or repair the Blower. luck

Thanks for the answer.
The Blower works, I have air (although in heat days I do not cool at all ... hehe) the Poblema is that I do not have cold or hot air. They told me that for the hot it can be the heater and I would like to know how I can try it works without disarming it. And for the cold that you may need refrigerant, but I don't know where it is going to see if it still has or not.

Sorry for not being more specific but, again, I just started in this self -taught.

Good morning, the automobile hot air and air conditioning systems are independent;
If you do not cool as probable that you do not have gas in the system as it happens in refrigerators that ultimately works very similar, it cools a radiator that when passing the air through it is cooled, for that you have to consult with a unespecialist in air conditioning that reviews the system that does not have any loss and loads the gas again.
For hot air it has the contol in the panel that indicates cold blue (ambient temperature) and red heat temperature that drinks from the water of the engine radiator, if the engine will not work for some reason at normal temperature the temperature of the heating is lower than the avitual that prodes to be another problem related to the thermostat or an object the heating radiator or the command key in poor conditions.

As the partner said the cold and customer systems work differently, now as the first measure the Tine vehicle an electro -ventilator that is that it is responsible for sending the air, whether hot or cold, the first thing is to check the fuses inside the vehicle this must be marked with: heater Ò aircon Always easy to disassemble (two or three screws and the connector and leaves), it is also easy to test it, (post and the battery in the electrvent motor terminals), if this rotates, then the problem can be the suiche that controls the electrontvent Ò the reostate that controls the speeds of said engine Ò in the worst case an interrupted cable interrupted in the electric branch. The most important thing is to make this electro -ventilator turn to turn to generate the flow of air flow
