When the a/c fan is on any setting other than the highest setting the air comes out cold. When the fan is set to the highest setting, it only comes out warm. This happens regardless of a/c or max a/c setting, regardless of fresh or recirculated air, and regardless of car speed. (2005 Mustang GT)
View 9 RepliesI have a 95 Ford mustang GT. When it is cold outside (Below 40 ish) it starts for about 1 second, dies abd the second time starts fine. has check engine light for lean exhaust. vacume pressure fine and been using injector cleaner but no improvement. replaced spark plug/ wires pcv valve.
View 5 RepliesSo roughly 2 months ago my ac wasnt blowing cold anymore and it was the evaporator, so i got a new one put in and recharged and it blows 50 degrees or colder now and it still blew that cold today. But today i heard a noise coming from the engine, so i inspected it and saw the compressor was turning on and off which it was doing right before i got it fixed 2 months ago, so I know its not the compressor but i know that's probably gonna go soon to. now its getting to winter so I don't need the ac.
Everything else is working perfect never had any problems with the car other then the ac, it does get used a lot cause but it never gets pushed passed level 2 out of 4. it has 90k on it and i was wondering if this is a major repair to just let it go and sell it for a reasonable price and pick up another car? or just fix it and hope another problem does not arise in 2 months. Like i said ive never had any problems with it before other then the ac. it still runs great and i can still floor it and she responds almost like new.
Simple question: Is it possible that battery problem/corrosion in battery cables would allow car to crank but not start on first try when cold? (Car normally starts on 2nd or 3rd try). I've read some places that if car cranks its not a battery problem but I'm not convinced.
Background:I have a 98 Ford Mustang (approx 140,000 miles) that occasionally has trouble starting. Car normally takes 2 to 3 tries to start first thing in the morning or if it has been sitting for a while. It always cranks but doesn't turn over. I had it in the auto repair shop, they said it had to do with IAC valve being stuck open. They recommended to replace throttle air by-pass valve. The repair was done and when I came to pick up the car I heard it take three tries to start before they brought it to me from the back. I asked about it, so the service advisor said he would go and talk to the tech, he said he talked to the tech and that there was a lot of carbon that he had cleaned out and maybe remaining carbon in the system caused problem, I got the idea that they seemed to think everything was fine if I had any problems I could bring it back. The car became even harder to start, now taking up to 8 tries. I brought it back and they said that the new IAC had to be adjusted to allow more air. I picked up the car, they said it was fine, but now it still takes 2 to 3 tries to start it first thing in the morning.
In the past, I have had trouble with battery and battery terminal corrosion, have had new terminal ends put on my battery a few times, last time was probably about 6 months ago. Terminal ends look very corroded again. I'm thinking about just asking them to replace the battery cables and see what happens.
AC works, but only drops temp by 15 degrees. Pressures 40/150 after adding some 134a.
Compressor runs continuously at idle. (I don't know if this is correct or not.)
Not sure what the issue is.
I have a 2003 Ford Musang 3.8L v6 when I start my car for the first time of the day or after several hours of sitting the car idles high between 1000-1300 RPMs for approximately 15-20 seconds after that it idles down to 600-800 rpms. I changed the spark plugs wires air filter not sure what else it could be no Check engine light.
View 1 RepliesI have a 2011 Mustang base with the V-6 engine and 6 speed transmission. It is my summer car, getting fewer than 3,000 miles on it per year. I take very good care of it. My question is what is the mechanical knocking noise I am hearing on cold starts? It continues for about 5 minutes until the engine is fully warm, then stops. The noise comes from the valve cover area. It clearly is a noise that cycles with the movement of internal parts. Is it normal or could be something serious. The car only has 10,000 miles on it (it was sold in 2010 as a 2011 model, so it is 5 years old now).
View 11 RepliesI got a 2002 mustang v6 and I hadn't flushed the coolant since 5 years ago so I decided to take off the radiator cap off too check the status of the coolant. As I took the cap off, coolant started to slowly spill out of it so I quickly put the cap right on. What causing this? My car was already cooled down and it can't be a head gasket problem cause I don't see white smoke. And I don't see any leaks from hoses and water pump . I park my car outside could it be the sun heating it up and making the coolant flowing out when I take the cap off? What causing this?
View 12 RepliesI 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 RepliesA cold engine crank will turnover and start normally. But stop to run and errand or grab lunch...and the warm 302 2 barrel engine will turn over very sluggishly, lke the battery is dying. If you wait until the engine is cool, an easy start is assured but that takes hours! A local repair shop has rebuilt the carb, the battery & cables are new, and the starter works fine when engine is cold. My local repair shop is out of suggestions. It seems to work a little to hold the gas pedal down on the floor for a warm engine start....but engine still turns over sluggishly when trying to start when warm. Now If I drive it.....I just drive it around town a bit then back home ...unless I stay several hours somewhere while the engine cools....but that's not fun. It is a convertible, fun to drive...and this problem needs to be solved.
View 14 RepliesSo I went on a trip with my 7.3 PSD the other weekend. It was a 4 hour drive. After 3 hours of driving with the A/C on, the air temp started getting warmer to the point were it seemed like the A/C wasn't working at all. After reaching our destination we didn't drive the truck much or use the AC for 4 days. On the trip home, the AC worked perfectly for the first 3 hours. Then again, the last hour it started to warm up like the AC wasn't functioning at all.
View 1 Replies1999 F-150 5.4L. I just removed the clutch fan and installed two electric fans about two weeks ago. The same evening, I took a short drive and noticed the idle was way higher than it normally is. Its idling about 800 to 900 RPM. Now, the weird part.....Startup is normal, as in the idle jumps up for the warmup, then drops to the normal 600 to 700 range. after a short drive, the idle is high and noticeable at a stop.
Sometimes, if I let the truck idle, after about 10 mins or so the idle will slowly start creeping up a little at a time till it hits about 900 or so and will level off. I have tried the IAC, I have tried disconnecting the battery and letting the PCM reboot, I have checked ALL my vacuum lines, I have checked my TPS sensor and voltages, checked my MAF sensor and voltages, fuel pressures, everything I could think of...
I hooked up my scanner (Auto X-Ray 6000) and checked all my running data, nothing really sticks out to me as outta whack. No codes set..
Here's the situation....It blows cold for about 5 mins, then the air starts to warm and stays warm. I just bought the truck 06 350 crew cab and they supposedly charged the system. I'm wondering if it has a leak but it should start out blowing warm air? I just wanted some thoughts before I start throwing money at it.
View 1 RepliesMY 2000 Ford F150 4.2L v6 is running cold. I bought it this summer and it ran a hair above the cold line on the temp gauge. Now that it is cooling off it doesn't come off the cold line. I have drove it for an hour and it never move. The heat is barely warm. I thought it may have been a stuck open thermostat so I changed it out with a 195 and it did not work. I can let the truck run parked for 15 minutes and still be able to grab the hose leading down to the thermo. What is wrong? The guy I bought it from used it to pull a small boat. He said it started running hot when he would pull with it so he had a new radiator, thermo and clutch fan installed. Then he said the truck ran on the colder side. Now the thing just runs plain cold!
View 1 Replies2001 F350 7.3L with 140K. Have had it for 7 years and this has never happened. I let the engine warm up (I'm in Cheyoming and it gets cold!). I'll have warm air coming out at all settings (foot, dash, combo, etc) for a few minutes, then the air turns cold!
I've checked the actuator and blend door and they seem to be working properly. The heater hoses going into the firewall are not particularly hot/warm. Is there a valve or thermostat that could be shutting water off to the heater core? Cause that's what it seems is happening. Like starting off in the shower with warm water . . . then someone gradually turns it to cold. Then next time I get in, warm air to cold again!
I have a ticking noise that seems to be coming from the drivers side of the engine. 2000 Excursion. It only happens when accelerating in every gear between 1400-2100. No noise at idle or park. Same noise when cold or warm, again only when accelerating. Goes away when you take your foot off gas. New exhaust studs, exhaust does not seem to be leaking, no carbon build up anywhere. No engine codes. Truck runs great and no loss of power. V10 with 120 k on it. Really annoying.
View 14 RepliesGot a 13 f150 with the 5.0. I bought it used with about 14 thous kms, now it has 17. Ever since I owned it I noticed the idle was a bit jumpy warm or cold. I didn't really pay any attention to it as it wasnt throwing a CEL or anything but now that I have a roush exhaust and intake I have started to notice it a lot more....not that its worse but at idle my truck sounds like a boat. Weird comparison I know. It seems like it'll jump within +/- 200 rpm @ idle which IIRC is 1K rpm.
View 7 RepliesThe front a/c blows cold air but the 2nd row and back blows warm. Yes the temp dial is on cold on both dials. Is there a separate a/c clutch that I dont know about to ck the air gap? Is there a separate port to put freon in besides the front. I need to get this fixed because with my bulldogs in the back the heat will kill them.
View 14 RepliesI have a problem here which isn't funny around 30F. The engine temperature act quite normal after a cold start, but the heating inside is disabled somehow. So I can select any temperature in the front and back, but it stays cold.

AC will blow cold, then shift to blowing warm, muggy air, then back to cold. Seems to be some relationship with throttle movement. Cruising steady ac seems normal. Multiple throttle shifts in changing traffic seems to trigger the warm air. Once accelerate back to normal cruise, can feel clutch/compressor shift and blows cold again.
Any ideas? I have read a possible cause can be the ac clutch can wear and need to remove spacers? Is this a DIY job? What about the ac clutch relay switch? On reading an online repair manual, seems that the clutch is magnetic, and if no battery power to clutch, it removes itself from compressor?
Just had an EGR delete kit installed. Any relationship to this and ac problem?
I noticed this evening that my low pressure oil pressure was much higher than normal. I have a LPOP gauge that typically reads 12 psi or so at idle This evening I was seeing 75psi with a warm engine. Every little acceleration pegged the gauge over 100psi.
The factory non-functioning gauge says that everything is normal.
I am about due for an oil change. I was thinking that I would change the oil and filter as soon as possible and temporarily plumb in my mechanical gauge to see if the high pressure reading is real or not. I replaced the stock LPOP about 3 years ago with a melling and everything has been golden up until now.
