Do you think that the heater core heat is being absorbed into the evaporator core & causing the pressures in the system to rise? I also did a quick test this morning when things were pretty cool: 1. Low & high: 50psi & 300psi (started at 48psi & 260psi) 2. I didn't measure vent temp ...

What do you mean by re-heating problem? Also I hooked up the scan tool last night & noticed that the evaporator temp reading was 26C when the vent temp was 12C. I understand that if the sensor was faulty & gave a reading of -12C (like I have seen in a Nissan Juke) then the AC compressor will...

A digital thermometer was used to measure vent temp on the passengers side - the side that is not/least affected by the mixing of heater core air due to a faulty blend door/flap FIRST TEST: 1. Drove the car from work to home @ 6pm with 'Max AC' setting on 2. Vent temp dropped to 11C, 4 minutes into ...

Before I post the readings, as per request, here are some photos showing:

1. The condenser outlet junction that branches into two pipes
2. The black insulation tape placed on the condenser I/O from which temp readings were taken

Where do they go to?

The branch going up goes to the high side service/gauge port
The branch going to the right (with HPCO switch/sensor) goes to the TX valve

Just re-read my second post and there is a mistake. The yellow circled pipe is the condenser outlet which has the two branches. The red circled pipe is the condenser inlet. In the photo with the alternator, the turbo is behind & lower than the alternator. Can’t see it because it’s covered by a h...

I've had a look at an aftermarket catalogue & also google searched the genuine part number for the AC compressor & yes there is no AC control valve for this model Ford Ranger. It is also a TX valve system & there is no accumulator - the dryer filter is built in to the condenser. I've att...

Hi, 2017 3.2L (P5AT) Ford Ranger, dual climate control Only 45,000km (~24,000mi) and the AC goes warm sometimes. I can confirm this AC system has never been touched prior to the AC issue. Took the car for a spin yesterday around 5pm (ambient temp 29C & about 90% humidity). AC was cool but then f...

Hi John & tbird, I'm going to take some time to read through the forum but seeing as this is Ford Ranger related, I thought I'd shoot a few questions your way first. Another Ford Ranger came in which another technician had previously recommended a fan clutch & dryer filter. After the repair ...

My last question to close off the thread is with regard to low & high side pressure readings when revving the engine. If I increase my rpm to 1500-2000 rpm then I would expect my low side pressure to drop & my high side pressure to rise, correct? I also have a Corolla & I revved the engi...
