Front A/C no longer blowing

Good evening,

There is only one compressor for the A/C system It does both the front and rear.

It does sound like the blower motor is bad but needs to be confirmed. You need to check for voltage to the blower motor to be sure it has power.

I attached a wiring diagram for you to do some checks. You can use a test light for these tests.

Roy

1. Disconnect and isolate the negative battery cable.
2. If equipped with a trim cover (2), remove the two screws (1) that secure the trim cover over the blower motor power module (3) located below the right side of the instrument panel and remove the cover.

3. Disconnect the two wire harness connectors (1) from the blower motor power module (2).
4. Remove the two screws (3) that secure the blower motor power module to the front HVAC housing (4).
5. Remove the blower motor power module from the front HVAC housing.

How would i access the entry to the blower motor? Is it inside the car under the dashboard of the passenger side?

That is correct.

Under the dash by the glove box. There may be a cover on it or it will be right there. Check the looks of the new one when you get it so you will be able to match it.

Roy

Thanks so much. i have been scouring the internet with little to no luck. I appreciate your speed too lol!

You are welcome.

Always glad to help.

Roy

Hey Roy, I am back. So, we replaced blower motor, resistor, then ground out pig tails weren't working from the controls, once we corrected this issue we have air.. bad news it's hot air in both the front and back, but the compressor is kicking in.. I'm thinking blend door actuator or expansion valve. Can you let me know what you think?

Okay, I need the high and low side readings of the system with the engine running.

When you change from hot to cold, can you hear the blend doors move? I doubt they all failed at the same time. This sounds like a Freon issue.

Roy

Let me check to see if i hear a change. Also, the blend doors are located under the drivers side? Just want to verify.

I was able to hear the door blends move.

Okay, then it is not the doors.

I need the high and low side readings. You can rent a set or buy a cheap set somewhere.

Roy

Where would i connect it? I'm heading to my auto parts store right now. What is it called? Thanks for helping me out. most the mechanics here want to charge $300.00 just to look at it and give a diagnostic, that's not fixing it or the parts.

There is a port for the high side between the compressor and the condenser.

You ask for A/C gauges.

Roy

The A/C discharge line (1) is the refrigerant line that carries refrigerant from the A/C compressor to the A/C condenser (2) and is secured to the condenser fan shroud (4) by a plastic retainer (3). The A/C discharge line has an integral fitting for the A/C pressure transducer (5) See: Refrigerant Pressure Sensor / Switch, HVAC > Components > Description.

NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

The A/C discharge line has no serviceable parts except for the rubber O-ring seals. The O-ring seals used on the connections are made from a special type of rubber not affected by R-134a refrigerant. The O-ring seals must be replaced whenever the A/C discharge line is disconnected.

The A/C discharge line cannot be repaired and must be replaced if found to be leaking or damaged.

I can't get the pressure, because no one in my town carries it.

Do you have a Harbor Freight? they have them and are the cheapest place to get them.

Roy

No sir.

Okay, a shop is your last option.

You could go online and get a set of gauges from either Rock Auto or Harbor Freight and have them shipped to you in a couple of days.

Roy

Okay, and lets say that the pressure is fine where would i go from there?

Your blend doors are working as you stated so the only thing we need to check is the pressures. I believe we are going to see the issue in the gauge readings.

Roy

I'm on my way to a guy that has one i can use. I'll send info soon.

Sounds like a plan.

Roy

All are open.

There is no freon in the system.

You will need to evacuate and charge the system.

Roy

We just put Freon in today that's the picture that showed green.

Never mind just checked and it says no Freon.

Charge the system and see if you see any leaks.

Roy

Getting Freon now.. will keep you posted.

Okay. give me the high and low side readings with the compressor running.

Roy

So tried the Freon and the gauge went into the red zone which i would think means it's full.

Freon is full, but no pressure.

Impossible. If there is no pressure then there is no Freon.

Who and how was it checked?

Roy

Went to put more Freon as suggested pushed the nozzle down and the gauge went to yellow, i pressed again and it went to red then down to yellow. I didn't want to press it all in there and put to much Freon because we had just put an 11 oz can in there earlier that day. Either the manifold gauge set (i ended up finding and buying, brand new) doesn't work or something is wonky

Okay, the third hose attaches to the can to be added. Once you attach the can, then open both low and high side valves for the Freon to enter.

Do this with the engine off, not running

Roy

Thought i would update, seeing as you have been a huge help. Took to an actual repair shop, because we were tired of playing the guessing game. Ended up one of our hoses (that has been discontinued) had a hole in it where we couldn't see (ordered the part through Rockauto and will be fixed soon), also water pump was pretty beat up our guy said (which was replaced today brand new) and we also needed a new belt (replaced) he did say the old blower motor was shot along with the resistor and pigtails to the A/C. controls, so it was a multitude of different issues that wasn't going to be able to be done on our own, so we thank you for all the help you provided and will have our A/C going by tomorrow...

You are welcome.

Always glad to help.

Roy
