My 95 thunderbird makes a ticking after it is started,it continues for about 5 minutes and stops. Also it happens sometimes when I turn on the air condition. The heater also will not turn on. What could be wrong.
Heater does not come on for a few minutes on purpose. The system waits until engine coolant is warm so fan not blowing cold air on you. The ticking can be the heater waiting to get turned on (air door closed) if sound seems to be coming from dash. System should work right away if you use A/C though.

Sounds like the hig head-pressure cut=out is kicking in and shutting down the compressor. This is probably caused by not enough air being moved across the condensor coil (in front of the radiator). Check and make sure all the engine cooling fan components are in place and functional (fan clutch, shrouding, belts tight) and also check the coil for obstructions (Bug accumulation, road debris, litter). Clean the coil and radiator as much as possible at a self-service car wash, see if that doesn't help.
This can also be caused by an overcharged system (too much Freon). Sometimes when these symptoms first appear, the knee-**** response is to add another can of Freon, only to make things worse. If this is the case, I would recommend a system evacuation and service, replacing the dryer/receiver and pulling a 28mm/hg vacuum on the system, and then refilling with the proper amount of Freon, and cleaning the evaporator coils as well. This can only legally be one by an HVAC Certified technician, to insure excess Freon is not released into the atmosphere.
Hope this helps you figure it out, and good luck!

Check the vacuum. High mileage vehicles tend to lose vacuum. That's why the cruise control and AC compressor will sometimes quit working. You may be able to find another source for increased vacuum.

Your crank sensor may be really dirty and can't get a good signal from the reluctor near the balancer. Check the wiring harness to it as well. You may need a new crank sensor.

when u turn the key to run but don't start the fuel pump shuts off after 5 seconds + or - 2 seconds, this is normal, the common cause of no start on your truck is the TFI ignition module on the distributor, subject of many recalls for failing, also change the stator inside the distributor, use factory parts, aftermarket parts fail very quickly. here is a picture of the parts.
This is the stator
This is the TFI ignition module.

It sounds like you either have an condensor fan problem or low freon. The condensor fan is near the radiator. In some cases the radiator fan doubles as the condensor fan. So look there too.
