Will this meter diagnosis relay problems on vehicle air conditioners or do I need to purchase the more expensive version for that?

I.m not sure why you specifically mention relays on vehicle air conditioners, as if that would take a special meter. However, this little inexpensive meter does have the ability to measure volts, both AC and DC, ohms, amps, check capacitors, diodes, do a continuity check, and resistance checks. So, depending what you are wanting to check, I think it would serve the purpose just as well as a more expensive one, if you are worried about cost. I really don't know what else you would need for checking a relay, whether on a vehicle air conditioner or any other piece of equipment. Most of the time you either want to know !. is it getting power, 2.are the points open or closed, 3. is the power getting across the contacts, or 4. is the relay coil burned out or not. So yes, I think this would do what you want it to do, and for a good price. For home use, or a DIYer, this is a good little tool.

I misread your Q. Get the new cord. I bought one at a truck stop that was more expensive and it blew circuit breakers in two trucks. Buy the correct one to save money and hassle

Probably not. If the issue is that you have some blower speed, or only high speed working, the speed resistor is in the blower housing. you can swap another relay in the wiring block, they are almost all the same, to see if the relay is bad.

Not sure...I am not an AC guy...I just connected the wires and turned it on...If if helps, one of our units is a gas pack. Heat and AC in one unit. Works fine..

Check wiring, check 10amp fuse on back of headunit, etc. Make sure that it is installed correctly!

I am not a qualified A/C repair man. Generally you replace both to get the big power bill savings. The savings is big !

I don't use this meter for ac work. I checked the meter and the info I got with the meter ( which is not much). But it will not do what you want . sorry not much help. Bill

I think so, however please don't quote me. Check owners manual. If Guage shows error have unit checked ASAP for defective operation. This unit is very straightforward and should be simple to have repaired at the local level.

Won't be plug-and-play due to different connections. Could be adapted if they're the same type of thermosensor but this is 50/50 at best. Oregon Scientific does not disclose the necessary information online; perhaps their tech dept. would. If you've got a damaged unit just buy a new one; they're cheap.

if you have a separate potential relay and a start capacitor with bleed off resistor, then you have the best solution. make sure capacitor is matched to your compressor requirements,

No, this will read the code the car's computer is saying is a problem. You can look up the code on the internet and that may lead you to the problem. Tell your mechanic to fix it. This device just reads codes.

It is a standard 12vdc device. Install all depends on usage. If tying in to a oem system, then using a relay is preferred to protect it.

I,m not sure but I expect there is an incompatibility between the electronics of the motion sensor and the relay coil. If the relay works properly using an on/off switch, it is likely that the motion sensor not the relay is at fault.

Hi; I think this a "hit or miss" proposition. I received a unit that did not work with my 2003 Honda Accord. I then worked with their customer service to get a replacement sent, and that one works. Plus, in reading other reviews, I came to the conclusion this scanner appears to have trouble with older vehicles (pre 2004 ?), and not so much the newer (post 2005 ?) vehicles. The return policy is you have to pay return shipping to China, which far exceeds the cost of the scanner. So, if you buy the scanner and it does not work, you may need to be prepared to "contact seller" to try to get a replacement (as I did). Did you try the BAFX scanner? That brand worked the first time in my Honda.

Yes, I noticed that to when the first one arrived. I apologize but I have not had time to check it yet. I purchased several for use on a postwar Lionel model train layout to use as track block relays as noted from a 1956 Lionel manual. Please stay in touch and I will try to get you an answer. I also purchase some Huron HH52P relays and the coils are clearly marked "12V AC."

Depends on pulling amps of your air conditioner. Check your starting amps for the air conditioner. This is nice unit but might be to small

I would recheck the connections, and then the relay. You could swap the other relay if it's working properly.
