Replacing relay

I have and a/c relay which might be bad. I don't know how to remove the relay switch from the fuse box. When I tried to pull it out there was a lot of resistance. Do they come out like a fuse or is there a latch or something which needs to be released?

Short answer is yes.. Some of 'em come out like fuses. Most of 'em are latched in place.

Would have to look at it to be sure.

Is this a relay or a circuit breaker installed in a fuse box in lieu of a fuse? Relays are different than breakers, and are not generally found in fuse boxes.

If a breaker inserted into a fuse holder, yes they go in and out just like a fuse. If hardwired in (not in a fuse holder), they may be screwed or riveted to the circuit board or backer.

The item in question is a small 1 1/2 " x 1 1/2" black box located on a panel on the firewall above the radiators. There are 4 in a row in a small long black box. I'm guessing a picture would help so I will attempt to take one and post it to make things easier.

An automotive style relay has 4 or 5 flat prongs, a fuse has 2. This makes it feel that much tighter when trying to pull it straight up. Try rocking it as you pull and you may get it. Check numbers on the other relays, mine has 4 in a row that are all the same part number, that makes it easy to just switch them around to see if the problem moves with the relay. Good luck HarveyP
