Is the issue there when using heat and air-con?
If so, then check the blower motor and fan switch for fault.

Check any cabin air filter if fitted for clogging.

If only an issue with hot air flow, then check the heater matrix hasn't bunged up.

If only a cold air flow, then check the air conditioning car evaporator in the cabin for signs of clogging.

Clogging can be more of an issue in pet owner's cars as pet hair readily clogs up these two components in cars fitted with no interior air cleaner element/filter.

SOURCE: Front air condition does not blow cold. Rear air condition does

sounds like a damper door in the front not working properly, these are actuated by the front temp control, the door is operated by either a manual cable, and electric actuator, or vacuum. I hope this helps you zero in on your problem. Merry Christmas

The A/C relay is in the glove box behind a panel that indicate relay. There are three relays in there, the middle relay is the fuel pump and one of the out side relay is for the A/C compressor and the other is for the third brake light. Just can not remember which out side relay is the A/C so just swap the out side relays with one another. Good luck and hope this helps. Keep me posted.

SOURCE: secondary air injection pump location

under the radiator on the passenger side of the truck. There is a little splash guard you will need to remove to see it, The guard is held in with 4 15mm headed bolts, then you will be able to see the bottom of the air pump.

How much freon does my 2001 chevy blazer hold


Normally there is a sticker on the a/c housing or the accumulator. I would start with 2 cans which is 24oz and then add as needed.
You use the high and low gauges to judge when the system is full.
It also makes a difference if you vac the system first.
You'll have to over-ride the low pressure switch to keep the compressor running while you add the first can.
