2000 F250 7.3 diesel... It began doing this last summer. It will blow cold and freeze you out then it gets hot and burns you up. If you step on the gas pedal for a bit, it will go cold again. We have changed high & low pressure switches and added more freon. What else do we need to look into?
View 1 RepliesMy 2000 F250 SD 5.4 AWD's A/C wouldn't blow cold suddenly the other day. I confirmed the A/C relay (engine compartment, 3rd down from firewall)was "clicking" but compressor clutch was obviously not engaging with dash switch on Max A/C and engine running. When I take of the 2 wire connector to compressor to see if it is getting power, the truck won't start..if I disconnect the A/C compressor plug while running, the engine similarly quits. I have never had another vehicle do this on me before..I could unplug the compressor on my Jeep GC, for instance, measure 12+ volts with A/C ON w/car running and no problem with Jeep engine turning off.
I have searched for A/C wiring schematic w/o success. I checked every fuse in cab/engine for continuity since I don't know which ones might deal with A/C..jumped hi/lo pressure switch connectors with engine running/A/C ON w/o compressor clutch engaging. Clutch turns easily, have banged it a few times, and air gap looks good. More bizarrerly, I hooked the compressor to a 12V/ground via its 2 male prongs and didn't get the clutch to engage.
I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.
View 14 RepliesOk my 2000 Toyota Celica GTS is having 2 very bad issues.
1st - It is hesitating very bad when doing "cold starts" and nearly dies when I turn the A/C on (engine code reads : Random/Multiple Misfires on all 4 cylinders)
2nd - I have to put in 1 pint of Anti Freeze every single WEEK! It is not leaking on the ground as far as i can tell too.
I have a 2006 f250 and the heater will blow cold air unless you are driving in like highway conditions. If you stop or drive slow it blows cold air only. What is causing this???
View 3 RepliesMy dad has a 2000 f250 4x4 with the 5.4. he said his blower would only blow on high. I told him it was his blower motor resistor. i thought it was under glove box. he took it apart and said no but there was a little box thing with wires he took off anyway and put back on. I then told him it was under hood below a/c lines. he replaced old one with a new one from auto zone and replaced the pigtail( plug too) fan works on high and a little bit on low very very little when u switch it to medium it stays the same. High works great. So we replaced the fan switch. (Radio was a bitch to remove) and it still does the same thing. I checked all fuses . when I check the plug at the resistor there is power to the center pin it stays on when u switch to low and medium but when u turn high on power goes out( on test meter) is there something I am missing? the blower blows on high even when u remove the plug from the resistor. Is that normal?.
View 4 RepliesI'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.
View 9 RepliesI took my car in for an oil change a few months ago when I was told the belt going to my a/c compressor was missing. It must have snapped off some time in the winter. I got the belt replaced and when I go to turn on the a/c I can hear it engage but the air that comes out is no colder than just having the vent on. A friend told me I just need to recharge the refrigerant.
View 2 RepliesMy 2002 Altima A/C won't blow cold air. Took it to my mechanic who says all switches, fuses, relays, compressor clutch are OK and system has pressure, but the compressor is shot. In order to get a replacement that's guaranteed I have to get a receiver/dryer with it. Also says not to get a compressor from the salvage yard. I'm wondering if there are any other testing procedures that could be used to be certain it is the compressor....
View 4 RepliesNeed to know if there is a kit available to fix cigarette burns in seat upholstery? I bought a 99 f150 to use for parts on my 2000 f150 and I want to use the drivers side seat. The previous owner smoked and there are a few little burns in the seat. Other than getting the smoke stink out, and the little holes. the seat is in great condition. The lumbar support is broke in my 2000s seat, and the seat cover is torn. that's the reason I want the "smokey" seat.
View 4 RepliesI have a 2000 Isuzu Rodeo with 230,000 miles. The A/C is cold when first turned on after start up, warm or cold engine. After about 5-8 minutes running on a sunny day, driving or at a stop, it starts blowing warm. If I shut the A/C off and leave it off for 30-45 seconds, it will blow cold again. On an overcast day it will blow cold for 15 minutes or more.
View 1 RepliesJust had the truck in the dealership for a bad blend door/ heater core case. Heat would only blow out warm on the passenger side, blows cold on drivers side. Dealership replaced the case, heat works normal on both sides now. It was a little warm out yesterday so i turned on the A/C, frosty cold on passenger side, warm on drivers side, temperature does change when i select different temperatures (dual zone.)
View 1 RepliesMy 2000 Echo's A/C didn't blow cold. It turns out the low side pressure was fine, but the compressor wasn't turning. I read somewhere that the A/C compressor's clutch eventually wears down so it doesn't grab the pulley anymore, and that sometimes removing spacers can move the clutch enough to allow it to grab. I took off the bolt on the compressor pulley and the spacer fell off. I put the bolt back on, and now I'm COOL!
View 2 RepliesI have a 2000 Toyota Avalon. The A/C will only come on if the switch is turned to full blast, but even then it makes a really loud grinding noise and does not blow very cold air. Is this a compressor issue or blower motor? I am assuming the switch is bad since it only works on highest speed, but could it be something else causing this also?
View 3 RepliesI have a 2000 yukon and the climate control stopped working. The defrost works just fine but the heater/ac stopped working nothing blows out from my vents when ac/heater setting is on. I checked all fuses and wires and everything is ok and connected. I just replaced my cd player and the next day climate control stopped working. I went back and checked the wireing of the cd player as well, everything is fine. Would i need a new climate control, or senser or is there a fuse on the heater itself.
View 1 RepliesI am wondering why my 2000 Ford Taurus experiences gas line freeze on a handful of occasions each winter, when our other vehicles never have this problem during our winters. It doesn't get extremely cold here, I live 50 mi south of Indianapolis, IN. Last winter I had this problem on a few occasions, and basically just waited for the temp to warm up above freezing, and the car started. Now it has happened again this year, with temps down in the high teens/low 20's. Car is parked under a carport at night - my battery is cranking strong, my fuel pump is doing it's humming noise when the key is turned 'on', tank was filled a day or two before this happened, and our other vehicles are starting just fine. We do use Heet in our gas tanks during the winter, but I hadn't gotten around to adding any to my tank before this incident. I have lived in northern Wisconsin and the Chicago area, and never had this happen to my old beaters back in those days....what is the big problem with the Taurus?
View 19 RepliesWhen I took my new used car to the mechanic, complaining how there must be an oil leak cause well by now 9 bottles of oil in 7 weeks time have been put in, the mechanic told me the engine is burning the oil too fast. He said something about the piston, but I got all confused. He also said that the only way to fix this is to replace the engine, but he recommended not to cause it would cost more than the car is worth. This is a 2000 Toyota Corolla. Why this is happening and what i should do about it.

View 14 Replies2000 Dodge Neon having issues with freeze plugs falling out. Have replaced at least four freeze plugs over the last year and a half. Is there a solution to avoid constant replacement? Neon has about 135,000 miles. There is no warning when a plug is about to fall. Research shows freeze plug issues are not isolated to the Neon and perhaps copper plugs are the answer.
