My turning signals & hazard flashers just stopped working during a very heavy rainstorm yesterday. The brake lights and headights DO work, though. Also, my A/C is not blowing out cold air. I think some fuses may have blown. Is there an easy way to find out which ones are causing the problem, other than removing and examining each of the many fuses on the panel? (I don't have a fuse-puller).

Re: Turning signals, flashers not working
You can use a pointed nosed pliers (or similar) to remove fuses..... The rain would not effect the turn signals unless you had a water leak into the flasher unit itself !
The A/C has to be fully charged to blow cold air and would not be on some days and then off the next. the refrigident gas would not change because of weather conditions. .........
A simple test lamp will indicate which fuse is functioning or otherwise without removal of same ! Good luck

Have you checked the bulbs already?
Don't know what kind of car you are dealing with here.
Most vehicles - the brake lights and rear turn signals share the same electrical circuit to the rear tailights. Usually the turn signal switch will separate which signal goes to the back.
Do your brake lights work? Is there a High mounted stop lamp and does it work?
I have seen a Hazard Switch be ON and fuse blown causing the Hazard Flasher to be inop - which prevented the turn signals from working. Turning OFF the hazard flasher brought back the T/S.
Check the rest of the lights - see what does and doesn't work - and do the front turn signals flash? Stay On? Or flash really slow?
Let me know what you find out and if this helps you at all.
IF THE TURN SIGNALS STILL WORK IN THE FRONT, THAT MEANS THE FUSE & THE FLASHER ARE OK. IF THE SIGNALS DON'T WORK AT ALL CHECK TURN SIGNAL FUSE & STOP / BRAKE FUSE. ARE YOU SURE THE CORRECT BULBS ARE BEING USED?
Probably the flasher, as I think you have a separate flasher for the turn signals under the dash above the brake pedal. It is probably next to the hazard flasher. If you can't find it, turn the hazards on and follow the sound. The turn flasher is probably next to the hazard flasher. Please let me know if this isn't the problem or you have more questions.
If you activate the turn signal switch and you step on the brake pedal, the turn switch (on the steering column) deactivates the brake light to make the signal light more visible. The bulb for the stop and turn lights is the same.
Turn hazard lights ON. If they don't blink, replace turn/hazard flasher, If one or more lights don't come on, replace bulb.
Check fuse and circuit wiring for broken or loose connections. If all looks fine, check following:
If front turn lights work fine, check brake/turn bulbs.
If turn lights come on but don't blink, replace turn signal/hazard flasher.
If front and back turn lights don't come on, replace switch on column.
Have you tried a heavy duty flasher? Also, if your signals & brake lights are 2 different bulbs, as in amber for signals & red for stop, then you will need a small in line converter to separate those 2 as most vehicles use same bulb for signal & stop.
there is a ground problem, most likely in the tail unit itself, but a ground problem is hard to find and easy to fix. reground the system, the turning unit, and the problem should stop. About the hazards, I don't know...... some times in older cars, that is the way it works. because the brake and hazard element in the bulb is the same and the old cars used a break in the power, but the new cars use a break in the ground. any way, chase the ground down first, it is usually the cause.
