Question about 2002 Mitsubishi Lancer

1 Answer

A/C only works on 1,2,3; blower only works on 4

I've had a problem similar to this one. On mine there was a lot of water on the passenger side, and it seemed like too much water to be from rain runoff from the windshield trough, or whatever it's called. It was an unusual color, though. It might have been rust, because I replaced a rusty a/c blower motor.

Back to my current problem, the ac still doesn't work. It works on 1,2, and 3, but the blower doesn't. Then when I switch it to 4, the blower comes on and it's cold for a few seconds, but then it stops being cold. I'm racking my brain trying to fix this problem.

    Just to clarify, the ac compressor is coming on, on only the 1,2, and 3 speeds with no blower. Turning on speed 4 the blower works and the ac compressor stops.

The new blower motor is not connected correctly. Check the wiring and varify its connected right, if it is then the fan control assembly is faulty. You should be able to operate the blower in all speeds. Fix the blower problem first and I believe it will fix your ac problem.

Radio lift gate and blower not working


Concerning the blower in your navigator. I had a similar problem when I first got mine. The battery in the truck recently got changed and there is a series of vaccum hoses in that General vicinity. One I plugged the vacuum hose back in the blower motor blew out the vents. But to ensure this is it I would check to see if air is coming through the windshield defogger first. If no there may be a different issue, if yes that's most likely your issue. In regards to the tailgate you could have a faulty switch, or a short. Lincolns are notorious for electrical issues. The wiring harness has a tendency to get water near it on the older models. Your wiring harness should be near the kick panel on the passenger side. Check your grounds.

2006 hummer h3 has a leak on passenger side under the dash during a rain storm


My 06 was leaking during rain also. It turned out to be the sunroof. There are two drain tubes in the front of the sunroof that run the water down the corners to the ground and two drain tubes that drain water out the back corners. The water would seep around the glass, which is expected, but both of the tubes on the front of mine were plugged, and the water would overflow behind the dash and fill my floorboards. If my H3 was leaning to the left during a storm then the drivers side would be full of water. If leaning right, then the passenger side. I had to open sunroof and blow compressed air into the drain holes to clear them, but be careful, too much air will separate tubes from sunroof and then you will have to remove the inside paneling around sunroof to get to tubes and reconnect. You may only have one side plugged. you can test it by opening sunroof and pour a little water in the small catch pan in the front of the sunroof and see if it drains as expected (to the ground under the firewall on left AND right side). You can see the holes in each corner of catch pan to drain the water. Plug one with your finger, then the other to find the plugged side. Good luck!! Hope this helps!!

Buick Century 2001 blower motor


Your blower resistor is bad. It is mounted under the passenger side dash behind and to the left of the blower motor. These things burn out short out causing the fan to run constantly and then they just fry and shut down the fan. It is a hard little ****** to get to and you need 1/4 inch ratchet, 6 inch extension a 1/4 inch universal joint and a 5 mm shallow socket and lots of patients. LOL

We had freezing rain now the blower motor wont work on my 99 aler


I had a similar problem - except only High worked on mine. When we got the snow on Friday, mine stopped working altogether!

Well, the solution on mine, which I found somewhere online, was that it was the resistor. It was $25 at Pep Boys and it is replaced by taking out the glove box and dashboard foot thing (all by screws) and it unscrews by two screws and unplugs.

I found this detailed description for another type of car - but it is the same exact procedure (my brother replaced it on Sunday).

"To get access to the heater resistor you will have to take the passenger side glovebox liner out by unscrewing the screws holding it in place.You should see where 2 or 3 wiring connectors are secured.Look above and behind these connectors and you will wiring connector that appears to plug directly into the air circulation housing,but actually that is the resistor screwed into the housing.Disconnect the wiring connector and the2 screws holding it into place and it will pull right out.There is not a lot of room to work back there so you may have a little trouble getting to that right side screw.Good luck "

Erratic control panel


This is the solution if your car sometimes has unexplained water on the passengers side floor after it rains and the Blower is working erratic.The solution lies under the large black bezel/cover below your windshield wipers. Under this bezel on the passengers side is a piece of weather stripping that has fallen off. You will see it right away. If you fix this and replace your blower motor and resistor your HVAC will work correctly again. I spent a year trying to figure this out.

Just remove the bezel and check the weather strip. You will be able to see where it was by the discoloration. It falls off by poor design and allows water to seep into your blower motor shorting out the resistor and if left unchecked will smoke the blower motor also. You want to add some silicon sealant and replace the weather strip to it's original position.
As far as the blower motor and resistor it is not all that difficult to replace. You will have to lie on your back on the passengers side to get at it. It's very uncomfortable.

Good Luck !!!
