Mercury - Capri :: 1973 - AC Give Warm And Cold Air Progressively / Not Connected To Heater
Sep 3, 2013
Car: 1973 Mercury Capri 2.0, four speed. Lovingly restored over the past three years. The car has Ford aftermarket air conditioning, recently serviced with R-12 (past two weeks) and I have never used it until this past weekend (I bought the car and then restored it). We used it in 90 degree heat and this little car did great even in the mountains of W.Va (60 mph uphill with A/C!) But I digress. For five minutes after being turned on, the A/C cools as expected - a real champ -- no issues.
Then, it begins a cycle like this: The air starts to get progressively warmer for about 10 seconds. Then, there is a squeak, a drop in motor rpm as the A/C/ clutch engages, and it has cold air again for 20 seconds. Then the cycle again. This is the behavior whether at idle or at highway speed. It has its own two knob control panel -- not connected to the heater controls. The fan speed is on high and the "cold" knob is turned all the way cold. Turned "warmer" it does as expected - very little cold air. It seems like a thermostatic control is telling it to disengage the clutch even though it should not -- the cabin is cool but not cool enough to justify that.

I have installed an auxiliary electric fan at the radiator on our 1973 Mercury Capri and it’s controlled by an adjustable thermostatic switch. Wanting to know when the fan comes on, I wired an LED indicator light to fan side of the thermostatic switch and mounted it inside the car. Mission failure.
The light comes on just from leakage through the thermostat. Ok, I figured maybe this is an LED issue. But no, a test with an incandescent bulb showed the same issue.
If the pilot light is going to glow all the time (dim at idle and brighter with revs, by the way), then it’s no good for the purpose intended. A resistor, maybe?

I own a 1974 Mercury Capri and I am having trouble finding a master cylinder. Where I can locate one?

My 52 Mercury Heater fan is working now, but the air blowing out of it is not warm and this does not change when I moving the temp lever on the dash. Is it likely just the heater control valve or is there something else possible wrong? I'm not finding anything online about how these systems work and my shop manual doesn't give me much info.

Yesterday evening I drove through a flooded area of the road, probably about 1.5 feet deep. I did not realize it was quite that deep. The water came through the floor, and probably soaked my ECU.
The engine died, but will idle very rough. I doubt I got water in the cylinders, not much at least, because the engine turned over no problem. I also have an air filter that would be difficult to get too much water into from the way it is situated.
It is putting out white smoke that smells like gas (a lot initially, now not as much), and the engine is smoking a little as well...white, gas odor...I think it is coming out around the exhaust manifold.4
It is running very rough, sounds like from 2 cylinders, and after letting it idle in the hopes of drying everything out, I noticed that the fuel gauge is at empty...it was at 3/4 earlier.
What should I start by doing?

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.

The a/c and heater are not operating properly. Not cold enough and not getting warm. Low freon, compressor going bad?
On a brighter note...I've sat looking down into a volcano that could blow at any moment.

I had to replace the vacuum control for the heater in the dash panel. The fan worked good on all 4 speed settings but only in the defrost position due to the damaged control valve. The control valve works all position for the heater positions now. There is power at both sides of the heater fuse under the dash but no blower function. Is there a fuseable link elsewhere in the system to check. Is the fan motor only accessible to test by accessing the heater/AC under the dash on the passenger side. 1973 Crew Cab....

My 2007 es350 77k miles. Heater starts to get warm and then it blows cold air. What could cause this.

2007 GS 350 109,500 miles. My heater was blowing cold at idle and warm when driving so I took it to dealer. To my surprise, dealer says its a blown head gasket. No other symptoms. No white smoke, no smells, no warning lights on dash, and running fine. Just had VVT gear recall done last week.
Fortunately I have Lexus extended warranty good thru 125k miles and Feb 2014. I do my own maintenance (plugs, oil changes etc). Have records for all. But have not done coolant change (due at 100k).

My '06 GS450h has developed a fault where the heater blows cold at idle and low revs but blows warm when driving or revving the engine at a standstill. The coolant hasn't dropped at all and the car never goes above halfway on the temp gauge. Its starting to get frustrating now the cold weather has set in and temps dropping! Long journeys are ok as at high speeds it stays warm but short journeys are uncomfortable!
I just had a feel of the rad hoses and hoses that go into the matrix (engine side of bulk head) and matrix hoses feel warm (both of them), the top hose to the rad is warm but not hot and bottom hose is cold suggesting the stat hasn't opened yet. Its cold outside so getting the car up to temp is quite difficult without a long drive (rush hour at the mo).
Still I just had the car parked on the drive and cranked the heater up to max and held the accelerator for a while and super warm air blows out. The engine cuts back out as "normal operating temp" has been reached for battery mode and then the heater goes cool again! Still the bottom radiator hose is cool and top hose not massively warm. It has never overheated thus far and I drive 150miles a day back and forth to Reading from Cheltenham 4 nights a week.
Only thing I can think of is a sticky thermostat or water pump not operating sufficiently enough to circulate the water? Its getting colder and short trips where it used to blow warm air nice and quickly (within 3-5miles) are becoming unpleasant!

So the other morning I drive the 140 miles out of town to work for the week. when I pull up to the job site the cooling fans were revving really really high! never heard this before. then it went back to normal after I opened the gate and parked my truck and shut it off. I'm driving maybe 5 miles tops to the job and back to the motel every day. however that is far enough that my heater should be warming up and it's not even coming close to warm. it blows cold air. and to compound that I'm not sure the cooling fans are even working. they don't appear to be. Is there a connection here?

The engine cranks and tries to start when the battery is connected. It does this automatically, you don't even need the key or ignition to be turned on. The remote selonoid has been replaced so has the starter. The car does start and run when you let it but the starter remains engaged so its LOUD. I have bypassed the ignition switch by disconnecting it entirely, however the car still cranks and wants to turn on when the battery is connected.

2009 Matrix with 2Zr-Fe engine (233,000 km or 145000 miles).
Engine has been getting progressively harder to start in the morning, especially when it is cold. Once its warmed up then it starts no problem next time. Occasionally I get the dreaded P0304 code upon startup. Also runs a lot rougher but that's hard to quantify here, I'm just going by sound.
Decided tonight to go through a complete checkup and here is what I found:
1. Looked for a dead cylinder by idling the car and disconnecting each fuel injector one at a time - everything was as it should be.
2. Used my spark tester (OTC 6589) and tested each coil in turn (yes I had the tester connected to battery negative using a battery booster cable). Each sparked strong and correct colour.
3. Pulled all spark plugs and checked them for cracks, carbon tracks and electrode gap, all were fine.
4. Did a dry compression test.
- Uh oh , 2 cylinders (3 and 4) were @ 115 psi, 1 and 2 were at 150 psi (which is also low as standard spec for 2zrfe notes it should be between 157 and 199).
5. Did a wet compression test
- cylinders 3 and 4 now ended up at 150 Psi so that indicates worn rings or pistons?
6. I didn't bother with the fuel injector testing as it looks like the problem is with compression...
So, first, is my diagnosis correct? Could it be a bad head gasket?
Second, is there something in my procedure above that I could have done wrong? The car was warm but not hot. I pulled all spark plugs before starting testing. I didn't take much time between plug holes.
Third, other than rebuilding or replacing engine, are there other options or am I out of luck?

I recently acquired a 2003 Mercury Sable from a friend and there is a problem with the air conditioning. The car has digital controls. I select the Max AC button, turn the temperature all the way down (60) an the fan all the way up, but it only blows warm air. I can hear and see the AC compressor cycling fairly quickly. The clutch (I think) engages for about one second and it will reengage after about 5 seconds, but again, it only says engaged for about one second.
What could be the problem? I've read the AC system might not have enough pressure and needs to be recharged. Or... the orifice tube is clogged, bad AC pressure switch, or the actuator that closes the heater door might be disconnected.
How quickly should a properly functions AC compressor cycle? The car was not driven much over the past year or two as it was my friend's grandfathers. I may end up taking it to a shop but I don't want to get ripped off. How should I approach this?

This has to do with a rattle on cold startup from a gear connected with the VVT system. I have a 2010 camry that may be affected by this. It just past 60K miles so they probably will not cover it under warranty. Does the rattle get worse over time, or will it have an engine failure if it does not get fixed?

I have an 01 Mercury Cougar Sport Coupe that we bought from a friend for not too much, just to use as a daily driver. It's got a lot of miles on it, but it still gets good mileage, which combined with the fact that we didn't pay much for it makes it an okay car for around town.
Here's the problem. I live in Wyoming where it's winter nine months out of the year, and the heater core is apparently blocked. I made it all through last winter with this problem, but now it's intolerable. The kids call the car "the Red Icicle". My mechanic diagnosed the problem as a blocked heater core and tells me the only solution is to replace it, which costs something like $500. I can't work on the car as everything is too jammed under the hood to get access to anything.
Do I really need to replace the heater core? The whole car isn't worth much. Is there something I can put in the cooling system that will unblock the core reliably?

I am having a problem with the heater on my 98 2.7 Intrepid. Will not blow hot air when idling (just warm). After several minutes of driving with heat on air temp goes from hot to warm. It might just be me, but it seems like the air flow is cooler coming out of the defrost vents than from the dash/floor vents. Thermostat has been replaced (proper operation verified before installing). Had to replace gooseneck and heater coil supply tubing due to a leaking bleed valve. There appears to be NO air in the system.
Heater core was backflushed, there appears to be no restriction. Hose temp on exit line is approx. 15 deg. cooler than supply line when fan is running. Blend door actuator was replaced last spring (motor shorted). When temp control is moved from hot to cold temp changes drastically and door can be heard moving. On-board ATC diagnostics indicate all is good. Engine is running at normal operating temperature, not overheating or running cold. Is there a cabin filter or inlet supply for the air that could possibly be obstructed? Air flow seems adequate, not restricted. AC works fine.

I have a 2000 suburban with a 1500 motor and 300000 miles. Last year I replace the water pump and the thermostat. The heater would blow warm but not hot . But only when I start to drive. Yesterday I decide to change thermostat again thinking the new one from last year was faulty. Now the heater only blows cold air .

My heater quit blowing hot or warm air all of the sudden. I took my mechanic and they said it showed no codes and were afraid to mess with it so I took it to a dealership. They worked on it most of a day. Said nothing showed a code as bad, they got into it and found the air going into the heater core was hot, but it was cool coming out. They spent some time flushing the coolant and said they found some sediment in the coolant fluid. They were hoping to flush out anything clogging the heater core.
