SOURCE: AC not blowing cold air

Most likely the A/C system needs to be recharged with freon.
Most shops charge under $50 for this service.

SOURCE: AC will blow cold air for a few minutes then start

you have moisture in the system this causes your expancion valve to freeze up an stop working, thats why it works for sort time and when it de-freezes stars working again. you need to do a EVAC & RECHARGE with a good AC service equipment, specially attention to pull vacumm por at least 20minutes so you get all moisture out of the system.
Good luck

Air Condition not very cold.


The pressure on the low side it not very meaningful by itself.
What matters is the difference between the high and low.
The low normally can be up to 120 psi or so, and the high side can be twice that.
But when the AC is running, the low side should drop to less than when it is off.
But there could be lots of reasons for it not being very cold.
The pump clutch could be failing to engage. The release valve should be not opening. The air flaps could be letting heater air in instead of cold. The AC condenser fan fan or relay could be bad.
Etc.

To tell if the ac coolant requires replacement the car will not cool when the sun is out and at all time you might have to put the car ac in coolest to enable a little bit of cold air.

Also the back seat will not be cool except the car is running on the highway.

Gas might be leaking somewhere.

Good luck

Temperature gauge fluctuates and the heater blows cold air


Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.

HYUNDAI TRANSMISSION


1. Drive the vehicle until the fluid temperature reaches normal operating the usual temperature [80-90°C (176-194°F)]. 2. Place the vehicle on a level floor. 3. Move the selector lever sequentially to every position. This will fill the torque converter and hydraulic system with fluid, then place lever in "N" (Neutral) position. 4. Before removing the dipstick, wipe all contaminate from area around the dipstick. Then take out the dipstick and check the condition of the fluid. The transaxle should be overhauled under the following conditions. a. If there is a "burning" odor. b. If the fluid color has become noticeably blacker. c. If there is a noticeably excessive amount of metal particles in the fluid. 5. Check to see if the fluid level is in the "HOT" range on dipstick. If fluid level is low, add automatic transaxle fluid until the level reaches the "HOT" range. Transaxle fluid: GENUINE HYUNDAI ATF SP-II, DIAMOND ATF SP-II or AUTRAN MMSP-II. Low fluid level can cause a variety of abnormal conditions because it allows the pump to take in air along with fluid. Air trapped in the hydraulic system forms bubbles which are compressable. Therefore, pressures will be erratic, causing delayed shifting, slipping clutch and brakes, etc. Improper filling can also raise fluid level too high. When the transaxle has too much fluid, gears churn up foam and cause the same conditions which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle fluid. In either case, air bubbles can cause overheating, and fluid oxidation, which can interfere with normal valve, clutch, and servo operation. Foaming can also result in fluid escaping from the transaxle vent where it may be mistaken for a leak. 6. Be sure to examine the fluid on the dipstick closely.0f3ac6e.gif
