When i turn my heater on, the ac come on instead. It does not matter what position any of the dials are on as soon as I turn the blower on the ac comes on. I do not see anything obviously wrong with the controls. All turn as they should nothing is striped. I have the 3 dial control setup no auto heater controls at all. and nothing is digital.
View 2 RepliesWe have a 2010 Prius, and I can't remember if AUTO just works on AC. or is suppose to work for controlling heat also. (Doesn't seem to) Nothing in book, and search turns up nothing.
View 19 RepliesI have a 2000 Limited Ex and was wondering can upgrade the heater controls to the digital controls. What would have to be done to accomplish this task?
View 7 RepliesI really would like to add steering wheel controls on my 2001 expedition. I only have cruise controls on there now, and don't want to add that little stick on remote thing... Anyway to possibly make dual use of the cruise control buttons already in place? All I really care about are volume controls anyway.

View 3 RepliesI don't know what it is but it comes on when the air is turned on inside the truck. Heat or A/C doesn't matter and its coming from rear passenger side by the window under the plastic molding. I thought it was a secondary blend door but as I know it the truck only has one.
View 1 RepliesMy 1968 F250 blows hot air with all controls set to off. The truck is fairly new to me and I'm a complete newb with a wrench....or screwdriver.....I think this should be a fairly easy fix? Aside from that it does work well.....it just doesn't shut all the way off.
View 1 RepliesTo kick off the coldest week (so far) of the winter season, I noticed a problem with the heater controls in my 06 Explorer with manual temp. controls. No matter which fan settings I select (defrost, panel+floor, etc), air does not blow through some of the vents. I can hear the fan working and air flows through the defrost vents and through the floor vents, but the there is no airflow through the vents below radio and round vents on the far left and far right sides of the dashboard.
Perhaps related to this problem, a couple months ago I replaced the blower motor resistor because fan speeds 1 and 2 did not work, only 3 and 4 worked, so whenever I would turn on the heat or A/C, it was on full blast all the time. After replacing the resistor, the issue was resolved and all of the speeds worked well. I guess I just never realized the issue with the vents, or maybe the problem happened because I replaced the resistor?
Since I'm not too knowledgeable with the climate control circuit, I'm not too sure where to begin, perhaps the switch or blower motor?
I have a 2000 F-150 and my lights to my gauges and heater controls quit working. I checked all the fuses inside and under the hood. All good. I swapped a few relays around and no luck. I tried replacing the headlight switch and that did not work. I checked power to the gauges from the headlight switch and there is no power, I then ran a hot wire to the wire that powers the gauge lamps and they do light up, so it is not a bulb issue. I assume I am not getting power, but do not know where else to look?
View 14 RepliesNo matter where I put the selector it blows out the floor, the defrosters and the air cond vents, which I have to keep closed. It doesn't switch the air flow anymore. What gives?
View 4 RepliesComing home from work tonight, Radio turned down, Air off/Heat off. Whats the sound coming from the dash around the radio/heater controls/ vents? Can't really explain the noise, but its like a boiling/clicking/scratching noise.
View 14 RepliesMy truck at idle sounds like it has aftermarket cams and the exhaust coming out of the tail pipe smells really rich. when driving down the road my heater controls default to defrost. Also when I fill up with gas it takes forever to get it to fill all the way. I am lost on where to begin with the problem [ I did check the tank vent hose and their is no blockage] Possible vacuum issue?
View 10 RepliesOn my 2000 E.B. I have NO A/C at all. All vents on the dash, regardless of vent, floor, defrost, ETC all blow hot air, even with the A/C on Max A/C. Also, all the rear vents for the rear HVC blow WARM air as well. I have no A/C in the back either. I don't hear any flopping around under the dash going down the road and I have checked the A/C compressor with the unit on Max A/C and the clutch appears to be engaged and the compressor appears to be operating normally.
I have NOT YET checked the A/C lines or dryer to see if they get cold, I will check that tonight, but I expect them to be getting cold because the Compressor does not cycle on and off, it stays running pretty much all the time. It clicks off once and again, but not very often at all (such as the case would be if the system was low on freon).
So, if the A/C lines are getting cold (if they are not, I will know my problem is compressor related, likely anyway), what this problem could be? From what I've read, if the Front blows hot, yet the rear blows cold, it's a blend door actuator or broken blend door, but that is not my problem. I have no A/C at all, everything blows hot.
I started feeling a slightly rough idle three days ago and yesterday the check engine light illuminated. When we read the OBD, it indicated a Cyl #1 misfire. Question is this. Can I replace a single coil pack (1/cyl), or do I ahve to replace all 8 as a set and why? 2000 Ford Expedition 5.4 L cyl misfire.....
View 4 RepliesI'm chasing a SES light on my mothers expedition. It had bank 1/2 lean and the 4 o2 sensor codes. So I put a fuel pressure gauge on it. At idle it fluctuated between 31-35 (rose and fell with a rough idle) as engine rise/falls. Rev it up to 15-1700 an pressure falls to 29-30, unplug the regulator and it pegs at 40 no matter idle-2000 rpm... does those numbers sound right?
View 11 RepliesI had my SUV (2000 Ford Expedition) tuned up. I'm losing about 1-2 quarts of coolant every couple of days. While I was having the tune up done, I asked the mech to try to find where the coolant is going. He couldn't. He did say that they'd pumped the system up to 18 lbs (it's got a 16 lb cap) and it held for 45 minutes, so I'm a little (little-little) less afraid that it's my head gasket. Questions are these:
1. Could my 16 lb cap be at fault? It got pretty gunky when I mixed the coolants (see my post - Don't cross the streams).
2. Could my rear heat exchanger be leaking and where would the coolant come out? It's got rear air and heat that's controllable form the second seat.
I never see water on the ground or dripping. No white exhaust to detect. Doesn't run rough at all at startup. In other words, none of the traditional head gasket indicators.
2000 Expedition. If speeds are under 40 mph and the air temp is above 85, my AC does not seem to work well. On the highway, it seems to work very well. Recently replaced with no change in performance:
Fan clutch
Water pump
Radiator
I've also degreased and hosed out the condenser. The AC system has been checked (by a friend with a set of gauges- but is not a professional) and a small amount of refrigerant was added. Still no improvement. Any obvious other things to check?
My parents have a 2003 Pontiac Grand Prix. The blower that controls the a/c and the heater does not work consistently. It just works when "the spirit moves it." I took it to a mechanic today. They didn't even look at the car. They just went by my description of the "symptoms" of the car. According to the place I went, it needs the whole nine yards (naturally). How could they tell what was wrong without examining the car?!
View 8 RepliesHaving a problem with my 2000 Expedition AWD/4WD. When I'm braking to a stop, there's a metallic clicking coming from my LR wheel. Doesn't matter if brakes are applied or it's rolling free. Starts at about 8 mph and stops at around 2-3. Had a broken parking brake cable, but clicking is still there after replacement. What's next? Wheel speed sensor, perhaps?
View 2 RepliesI bought a 2003 Nissan Frontier XE that is in really good condition. The only noticeable problem is that the knob that controls the fan speed of the heater and A/C only works in the 3 and 4 positions. I can here the belt engage when I turn the knob to 1 and 2, but no air comes out. So basically, July in Tennessee, it's either very hot in my truck or very cold.
