The best high pressure AC switch depends on your vehicle and the exact function of the original part. For many Buick, Chevrolet, GMC, Cadillac, Pontiac, and Saturn applications, the replacement sensors listed for OEM numbers 1551343 and 13587668 are the closest match. The A-Premium switch is aimed at select Ford, Mazda, and Mercury vehicles, while the UAC and A-Premium cut-out listings are different switch types that require careful part-number verification.
| Product | Best For | Key Check |
|---|---|---|
| AC Pressure Switch Sensor, OEM 1551343/13587668 | Listed GM-family and other applications | Match the OEM number and vehicle |
| A-Premium High Pressure Switch | Select Ford, Mazda, and Mercury vehicles | Confirm reference number and fitment |
| AC High Pressure Sensor, OEM 1551343/13587668 | Replacement of listed GM-family sensor numbers | Verify connector and exact application |
| UAC Clutch Cycle Switch | Vehicles requiring this cycling-switch type | Not a universal high-pressure sensor |
| A-Premium Compressor Cut-Out Switch | Listed older Buick, Chevrolet, and GMC applications | Confirm it matches the original switch |
AC Pressure Sensor For OEM 1551343
This sensor lists replacement numbers including 1551343, 13587668, SW10093C, and several related part numbers. Its stated vehicle coverage includes selected Buick, Chevrolet, GMC, Hummer, Saturn, Cadillac, Ford, Isuzu, Mercury, Oldsmobile, Pontiac, and Saab models across multiple years. The manufacturer describes aluminum and plastic construction and corrosion resistance.
Best for: Buyers whose existing sensor carries one of the listed reference numbers and whose vehicle is included in the fitment information. It was selected for its broad stated application range. Caution: Broad year and brand coverage does not establish fitment for every trim or engine; verify the original part number before ordering.
A-Premium Ford, Mazda, And Mercury Switch
This A-Premium listing covers numerous Ford vehicles, including selected F-150, F-250, F-350, E-Series, Mustang, Ranger, and Super Duty applications. It also lists select Lincoln, Mazda B-Series, and Mercury models. Reference numbers include SW10035C, 1S4319, 6L3Z19D594A, and F5TZ19D594AA.
Best for: Owners of a listed Ford, Mazda, or Mercury vehicle who can match the replacement references to the original switch. Its detailed model and year list makes it easier to check a specific application. Caution: The extensive fitment list includes gaps and separate year ranges, so do not rely on vehicle make alone.
High Pressure Sensor For GM Reference Numbers
This pressure sensor lists OEM references 1551343, 13587668, 15-51343, 13502759, and SW10093C, among others. Its description says it monitors refrigerant pressure and sends data to the vehicle control system. It is described as an aluminum-alloy and engineering-plastic replacement with pin terminals.
Best for: Buyers replacing a sensor with one of the stated OEM numbers and seeking a listing that describes its pressure-monitoring role. Caution: The provided product information does not give a vehicle-by-vehicle fitment list, so confirm application and connector details before purchase.
UAC A/C Clutch Cycling Switch
This UAC part is identified as an A/C clutch cycling switch and OE replacement. The listed thread size is M12-1.5 female, and its description says it is tested to meet or exceed OEM specifications. A clutch cycling switch and a high-pressure sensor are not automatically interchangeable; their jobs and installation requirements can differ.
Best for: A buyer whose service information or original part number specifically calls for this clutch cycling switch. It is included as a related A/C switch option, not as a universal high-pressure sensor. Caution: Avoid choosing it as a substitute for a pressure transducer based only on the word “switch.”
A-Premium Compressor Cut-Out Switch
This A-Premium cut-out switch lists extensive fitment for selected Buick, Cadillac, Chevrolet, GMC, and Pontiac vehicles, including some older cars, trucks, vans, and SUVs. The product name identifies it as a compressor cut-out switch rather than a pressure transducer.
Best for: Owners whose vehicle application and original part identify a compressor cut-out switch matching this listing. Its broad older-model coverage is the reason it is included. Caution: Do not assume it fits every vehicle named; check the exact model year and original switch design.
Buying Guide: How To Choose A High Pressure AC Switch
How can you confirm the correct part?
Start with the vehicle’s year, make, model, and engine, then compare the original switch’s part number with the listing’s reference numbers. A match on the part number is more useful than a broad brand match. If the original number is unreadable, consult reliable vehicle-specific parts information before ordering.
Is a pressure sensor the same as a cycling or cut-out switch?
Not necessarily. A pressure transducer reports refrigerant pressure to a control system, while cycling and cut-out switches may control compressor operation in a different way. Match the replacement to the function and type of the part being removed. Do not substitute based on a similar name alone.
What details should you compare?
- Reference numbers: Check every available OEM or cross-reference number.
- Vehicle fitment: Confirm the exact model year and application, including listed year ranges.
- Physical details: Compare the connector, terminal arrangement, and thread information when provided.
- Part function: Confirm whether you need a pressure sensor, cycling switch, or compressor cut-out switch.
If fitment remains uncertain, have a qualified technician or parts specialist verify the correct component. A mistaken switch selection can leave the A/C problem unresolved.
Frequently Asked Questions
What does a high pressure AC switch do?
Depending on the design, an A/C pressure component monitors refrigerant pressure or helps control compressor operation. Check the specific part type to determine its function.
Can I choose a switch by vehicle make alone?
No. The listings cover specific models and years, and one make can use different parts across applications. Verify the model year and part number.
Are OEM reference numbers important?
Yes. Matching the original part number to a listed replacement number is a practical way to narrow fitment, though vehicle-specific confirmation is still advisable.
Can a clutch cycling switch replace a high-pressure sensor?
Not automatically. They may serve different functions and have different designs. Use the part type specified for the vehicle.
What should I do if I cannot identify the original switch?
Check vehicle-specific service or parts information, or ask a qualified technician to identify the part before ordering.
