Compressor not engaging r34 freon ok
I STRONGLY RECOMMEND AGAINST 'bypassing' your compressor relay switch. UNLESS of course, you're an EXPERT in automotive electrical systems.
You need an expert because that compressor relay switch carries HEAVY CURRENT [LOTS of AMPS], and if not done PRECISELY correct, WILL CAUSE A FIRE, which depending on circumstances could be devastating, and even totally destroy your vehicle!!!!!
The fact that you even ASK this question tells me that YOU ARE NOT QUALIFIED to "BYPASS" your AC relay!!!!!
The "PROPER" fix is to knowledgeably troubleshoot the related electrical system, and repair or REPLACE the defective part which is causing the failure.
Use a wire to connect the two openings parallel to each other just for flash. If you get a spark but no engagement then it's probably not the relay but the clutch. The clutch relies on the relay bringing the ground connections together. Find the grounds in the connector using a continuity tool or reading the diagram on the spade end of the relay, using a magnifying glass if necessary. They're hard to see.

When your R-134a runs too low it will NOT engage the compressor. You need to refill your a/c system before the clutch will engage, I also suggest finding the leak.
